Quality Desktop Cutout PhotoMask is an affordable, high speed mask cutting application that readily fits in the desktop publishing environment. It generates pro- fessional quality cutout masks, like a dedicated prepress work- station, but for the price of a typical desktop application. PhotoMask runs on the Power Macintosh™ as a plug-in to Adobe Photoshop™, and allows the viewing and editing of masks directly on the image. Very precise paths are created quickly and easily, and they are compatible with Photoshop paths. Easy Operation PhotoMask has three operating modes: 1. Auto (bitmap mask) mode A bitmap mask is created automatically by picking up a desired or unwanted color. A bitmap mask can be converted to a path anytime. 2. Semi-auto mode Bézier lines are automatically drawn at edge of the cutout image according to the reference color, in the area generally indicated by the cursor. The viewing window automatically scrolls during this process. 3. Manual mode The edge of the cutout image is traced manually. You can switch to semi-auto mode at any time to analyze the edge. High Speed Cutting masks with PhotoMask is several times faster than using conventional software. The three operating modes and quick image scrolling allow you to create complex paths easily. Moreover, paths can be edited at any point. High Precision PhotoMask creates paths on the display monitor and can choke or spread all or part of the outline by up to three pixels, in 0.1 pixel increments. You can get quality equivalent to actually cutting out images on film, to satisfy the most demanding requirements. Plug-in Convenience* Photomask is a Photoshop plug-in, so you can import or export files from the menu in Photoshop. You can use PhotoMask as a complete cutout tool, and also you can modify masks created in Photoshop to improve their quality. *Exporting file is implemented at release version. System Recommendations • Computer: Power Macintosh™ • System: 7.1.2 or above • RAM: 32 MB or more • VRAM: 2 MB or 24-bit full color video card.* *Some video cards may not work. • Photoshop: Version 3.0 Power Macintosh is a trademark of Apple Computer, Inc. Adobe Photoshop is a trademark of Adobe Systems Incorporated. PhotoMask Operation Guide 1. Installation 1-1. Insert the floppy disk into the Macintosh. 1-2. Save the PhotoMask plug-in icon to the plug-in folder in Photoshop. 1-3. Configure the memory to suitable size for Photoshop. Set the preferred size to double the size of your normal images to be cut out. E.g., to handle 5 MB images, the preferred size is recommended 10 Mbytes. 1-4. Set the displaying color to 16.7milion colors in the monitor of control panel. *for maximum performance. 1-5. Start up the Photoshop and open an image file to be cutout. 1-6. Select PhotoMask menu of Mask in the Filter menu. 1-7. The PhotoMask displays an image which is selected in Photoshop. ATTENTION -- This demo version can not save results! 2. The Path mode (semi-auto or manual). There are two modes. One is the semi-auto mode in which the pro- gram automatically finds the edge of the desired (object) area to create paths. The color sensitivity between the object and the back- ground can be adjusted to help in this process. The another mode allows manual tracing on the edge of the object image. Pictures often have some constant color like a gray in the background, and in such cases the semi-auto mode is the fastest and most convenient way. However, in some portions, where it is more difficult to tell the object from the background, you can switch easily into manual mode. 2-1. Before operating in path mode 2-1-1. Change from manual mode to semi-auto mode in the Path control menu. Manual mode is always set on start up. After changing to semi-auto mode, the semi-auto function is marked. • Command+F: toggles between modes. 2-1-2. Set suitable parameter in Edit menu. When selected, the Set parameter is marked. • Command+H: toggles to display parameters. Select a better number in the Smoothness to see a smoother rubber band (20 is normally recommended). This number affects the viewing of rubber band but doesn’t affect the amount of actual path data. A higher number is smoother but takes a bit longer to display. Select a suitable line in the Manual line type and the Semi-auto line type (Bezier C is normally recommended). • command+1: Line (straight line) • command+2: Bezier A (smoothest line) • command+3: Bezier B (medium smooth line) • command+4: Bezier C (closest line) Select a pixel value to get suitable color boundaries in Choke & Spread (0.2 pixel is normally recommended). Select a pixel value to get a better quality for paths in Smooth Level (0.75 pixel is normally recommended). 2-1-3. Enable the auto scroll function in Path control menu. When selected, the auto scroll function is marked. • Command+B: toggles to enable or disable. When the rubber band comes to the edge of the display window, the window will scroll automatically. 2-2. Operation procedure in Path mode 2-2-1. Set path mode. Make sure P mode change and RGB display in Select SEPA menu. Set on Semi-Auto function and Auto scroll function in Path control menu. 2-2-2. Zoom up the area where you want to start. Use the zoom tool and click the mouse. • Space bar+command key or zoom tool: Zoom in *Space bar should be pressed first. • Space bar+option key: Zoom out *Space bar should be pressed first. • Command+D key: Fullview (full image) • Space bar key: Scroll image 2-2-3. Select the start point to create first path. Click the pen tool. When the cursor is moved around the background of the object image, the first path segment appears on the color boundaries of image. Click the mouse to fix. *Move the cursor a little bit away from the boundaries. 2-2-4. Create the second path. When the cursor is moved around on the background, the rubber band appears. Select a suitable point for the second path. This determines the direction of path creation. 2-2-5. After third path. After third path, as the cursor moves, the rubber band is traced along the color boundaries. Move the cursor in the desired direction and click the mouse to create clipping paths. If the rubber band wanders in the wrong direction, use the delete key until get a suitable point and adjust the color sensitivity by using the Z or X key. Or use icon with up arrow or down arrow. • Z key (Down arrow): Find similar color to the background. • X key (Up arrow): Find different color from the background. The number is variable 0 to 126. 2-2-6. In difficult area. Use the manual mode to find color boundaries in difficult areas. In the semi-auto mode, change to the manual mode temporarily by holding the shift key. When the shift key is released, the semi-auto mode comes back instantly. Or change to the manual mode completely by using command+F key and choose a suitable line type by using command+1-4 if necessary. In the manual mode when using Bezier A (most smooth line), for example, the tab key can also change to straight lines temporarily. 2-2-7. Choke & spread function. In semi-auto mode, the rubber band can be adjusted precisely with the choke & spread function at the color boundaries by using the A or S key. Or use icon with up arrow or down arrow. • A key (Up arrow): Move edge inward (choke), if the progress is clockwise. • S key (Down arrow): Move edge outward (spread), if the progress is clockwise. *The increment for each keystroke is defined by the Choke & Spread menu (0.2 is recommended), up to a maximum of 3 pixels. The number is variable -3 to +3. 2-2-8. Close path. When the rubber band closes to the starting point, the cursor shape is changes to square. Click the mouse to close or use command+G key to close. 2-2-9. Editing paths. Click the screwdriver tool and click the mouse on the rubber band. • Click the screw driver: Paths appear on one closed rubber band. • Double click the screwdriver: All paths created appear on all (commnad+A) rubber bands. Select the desired path to drag or select two paths for editing. The paths which should be edited change from normal square to the filled square. Use A or S key for the choke & spread function to get exact rubber bands on the color boundaries. *The moving direction is different from the 2-2-7 definition but use a suitable key. Use the command+Y key (Open path) to re-create the rubber bands. Deleting is possible at any time by using the delete key. When use the command+N key (Invert), the filled paths in between two paths are changed quickly to another path groupe which was not selected. 2-2-10. Combine the open paths. While creating paths with the pen tool, click the pen tool or the screw driver tool. Open paths are created. After creating additional open end paths, drag last path or create paths to close two independent opened paths. 2-2-11. Undo (command+Z) is possible at any time. 2-2-12. To see clearly outline of cutout. Use white or black in Base color menu. •White: Background of cutout image is white. •Black: Background of cutout image is black. When use the apple marks tool with this function, the mask area created the paths is inverted instantly. (The mask part is changeable from inside of paths to outside.) 2-2-13. To see a number for creating paths. Use command+I (Path points number) in Edit menu. To delete this information, click the displayed number. 2-2-14. Convert created paths to bitmap mask. Convert created paths to bitmap mask in Bitmap mask menu, if necessary. 3. The bitmap mask (auto ) mode. The bitmap mask mode is good for complicated images, especially when the images have unnecessary fine parts inside of the image. This mode paints or deletes the bitmap mask to the desired color, adjusting the color sensitivity. Furthermore, there are some convenient tools, such as the paint can, the lasso and the scissors, to help create bitmap masks easily. Bitmap masks can be converted to paths and paths converted to bitmap masks. Very flexible operation is thus possible. 3-1. Before operating in bitmap mask mode 3-1-1. Change the path mode to the bitmask mode in the Select SEPA menu. Use command+M key to change. 3-1-2. Select RGB in the Select SEPA menu to view full color. 3-1-3. Set suitable parameter in Edit menu. When selected, the Set parameter is marked. Select a suitable pixel size in the Pixel Size to pick up the desired color. (3*3 is normally recommended). Select a better way in the Affine to get suitable desired color (threshhold is normally recommended). • Average: The desired color is defined by averaged value from all pixels in the pixel size. • Threshhold: The desired color is defined by averaged value from pixels except maximum and minimum values in the pixel size. *less influence by noise color. Select a ignored pin-hole size in the Ineffective area size. The unit is defined by the pixel length arround the square. (32 pixel is normally recommended). Select a suitable mask color in the Bitmask Color (red is normally recommended). Select a suitable mask density in the Effective Level (100% is normally recommended). Select a suitable color for the candidated mask area in the Matrix (blue is normally recommended). Select a suitable density for the candidate mask area in the Matrix density. (100 is normally recommended). *This setting should not be changed once set. 3-2. The function of each tool 3-2-1. The pipette Pick up the desired color and adjust the color sensitivity with Z or X key (arrow). • Click in the mask area: Define deleting mask area adjusting the selected color sensitivity. Yellow or orange area: Adjustable mask area to remain. Cyan area: Adjustable mask area to be deleted. Green area: No adjustable area without mask. • Click outside the mask area: Define painting mask area adjusting the selected color sensitivity. Yellow or orange area: No adjustable area with fixed mask. Cyan area: Adjustable mask area to be painted. Green area: Adjustable no mask area. 3-2-2. Paint can Paint or delete the mask in selected area. • Click after the pipette is picked up in the mask: Delete the mask (change cyan to green). • Click after the pipette is picked up out of the mask: Paint the mask (change cyan to yellow or orange). • Double click: Fix the designated area as mask after adjusting the color sensitivity (change to magenta). 3-2-3. Lasso Paint or delete the mask in traced area • Trace after the pipette is picked up in the mask: Delete the mask in the traced area (change cyan to green). • Trace after the pipette is picked up out of the mask: Paint the mask in the traced area (change cyan to yellow or orange). 3-2-4.

Eraser • Click: Delete the mask (to cyan) with one of 5 nozzle sizes in Draw size menu. *Holding the shift key down temporarily changes the eraser to the pencil. • Double click: Delete the bitmap mask (to cyan) in all the displayed image. 3-2-6. Scissors Designate free area, use with tools 8 to 10. • Click: Designate free area and the outline is flashing. • Double click: Display on the outline around the whole window area or display off the outline. 3-2-7. Small paint can in broken rectangle Display on/off outline, use tools with 8 to 10 • Click in the mask: Display on or off the outline of the mask and the outline is flashing. • Click out of the mask: Display on or off the outline in no mask area and the outline is flashing. • Double click: Display on all outlines in all the masks. 3-2-8. The 4 arrows (choke and spread the mask). • Outward: Spread the selected outline by 1 pixel. *small pin holes may appear. • Inward: Choke the selected outline by 1 pixel. 3-2-9. White circle with dots outside • With the scissors: Delete the mask in the designated area. • With the small paint can: Delete the mask in selected outlines or delete the dust marks in no mask area. 3-2-10. Black circle with dots outside • With the scissors: Paint the mask in the designated area. • With the small paint can: Paint the mask in selected outlines or paint the pin-holes in selected mask area. 3-2-11. Black circle without dots • With the scissors: Paint the mask in the selected area and delete other masks in whole area. • With the small paint can: Paint the pin-holes in selected mask area and delete the dust marks in other whole area (out of the selected area). *The pin hole size in tools 9 to 10 is decided by the Ineffective area size. 3-3. Operation procedures in Bitmap Mask mode 3-3-1. Paint the mask in whole area. Double click the pen tool and change whole area to the mask (magenta). 3-3-2. Pick up the constant background color (unnecessary mask area). Use the pipette tool and adjust the color sensitivity using the Z or X key to get the suitable area. Necessary mask area will be yellow or orange and unnecessary mask area will be cyan. 3-3-3. Fix the masked and unmasked areas temporarily. Double click the paint can tool. The fixed mask area will be magenta and no mask area will be green. 3-3-4. Delete more of the unnecessary mask. Pick up unnessarary point as mask with pipette tool. Adjust the color sensitivity using Z or X key to get a suitable area. Necessary mask area will be yellow or orange and unnecessary mask area will be cyan. Use the paint can, lasso or scissors tool to delete and change cyan to green. *The lasso or scissors tool are more useful for designating accurately. *The scissors tool needs the white circle tool with dots-outside. 3-3-5. Create more of the necessary mask. Pick up nessarary point as mask with pipette tool. Adjust the color sensitivity using Z or X key to get a suitable area. The necessary mask area will be cyan and unnecessary mask area will be green. Use the paint can, lasso or scissors tool to create and change cyan to yellow or orange. *The lasso and scissors tools are more useful for designating accurately. *The scissors tool needs the black circle tool with dots-outside. 3-3-6. Repeat 4 and 5 operations, if ncessary. Use command+E to see sometime the original color for image. 3-3-7. Make sure the Ineffective area size. (normally 32 pixels are recommended). 3-3-8. Delete pin-holes in the background (unmasked area). Double click the small paint can to display all outlines in all the masks. Use the black circle tool to get the final mask without pin- holes. 3-3-9. Edit small parts. Use the pen or eraser tool to make minor changes. 3-3-10. Make sure the smoothness level in the parameter. (0.75 pixels are normally recommended). 3-3-11. Convert the mask to a clipping path. Use the Bitmask to clipping paths in Bitmap mask menu. 3-3-12. Edit the clipping paths if necessary. Use the screwdriver tool as well as the path mode. This is not only one procedure to get bitmap mask. There is a procedure which is an oposite way above, like deleting whole area first and paint necessary area. Or if there are complicated parts inside of image, they are used by bitmap mode and the outlne is used by trace mode. To get final result, try suitable ways what you find. To exit PhotoMask, Cancel or OK. Copyright 1995 by Dainippon Screen Mfg. Co., Ltd. All rights reserved.
