<a name="1003426"> </a>The first step to creating an image in Corel Painter is opening a document. You can open a blank Canvas by creating a new document, work with an existing image by opening a file, place a file into a document, or acquire an image from a scanner or digital camera to place directly into a document.

<a name="999213"> </a>Understanding Resolution
</h3>
<p id="999214" class="Body">
<a name="999214"> </a>When working with images in a digital workspace, it is helpful to understand the concept and applications of <span style="color: #000000; font-style: normal; font-weight: bold; text-decoration: none; text-transform: none; vertical-align: baseline">resolution</span>. Resolution refers to how Corel Painter measures, displays, saves, and prints images-either as small squares of color known as pixels or as mathematical objects known as vectors.
</p>
<p id="999218" class="Body">
<a name="999218"> </a>A document's resolution affects both its appearance on your computer screen and its print quality. You can specify a document's resolution when you create a new document, acquire an image, and save/export a file.
</p>
<h5 id="999220" class="ToDoHead">
<a name="999220"> </a>Resolution and Screen Appearance
</h5>
<p id="999221" class="Body">
<a name="999221"> </a>Most monitors have a resolution of 72 dpi (dots per inch). Because of this, the Corel Painter display default is 72 ppi (pixels per inch). This means that each pixel in the Corel Painter image occupies one pixel on your monitor. The display resolution does not affect the document's actual ppi-only how the image is displayed on the monitor.
</p>
<p id="999228" class="Body">
<a name="999228"> </a>For example, a 300 ppi document displays at approximately four times its actual size. This happens because each pixel in the Corel Painter image occupies one pixel on your monitor, and the monitor's pixels are four times the size of the image's pixels. Put another way, at 300 pixels per inch, your document will be approximately a quarter of its on-screen size when printed. In this example, if you want to view the image at actual size, set the zoom level to 25%.
</p>
<p id="999233" class="Body">
<a name="999233"> </a>Keep in mind that if you leave the dimensions in pixels and then change the pixels per inch (resolution), the actual printed size will be affected by the change. Ifáyou set your document size in inches, centimeters, points, or picas and change resolution, the dimensions will not be affected by the change.
</p>
<h5 id="999234" class="ToDoHead">
<a name="999234"> </a>Resolution and Print Quality
</h5>
<p id="999236" class="Body">
<a name="999236"> </a>The resolution of output devices (printers) is measured in dpi and, in the case of halftones, lines per inch (lpi). Output device resolutions vary depending on the type of press and paper you're printing on. Generally, a photograph will be output at a crisp 150 lpi if printed on glossy magazine stock and at 85 lpi for more porous, and therefore more forgiving, newspaper stock.
</p>
<p id="999237" class="Body">
<a name="999237"> </a>If you are using a personal laser printer or inkjet printer, set your document size in inches, centimeters, points, or picas at the dpi specific to your printer. Most printers will produce excellent output from images set to 300 ppi. Your file will be output correctly, at the best resolution for your laser printer and at the proper size. Increasing the file's ppi setting does not necessarily improve the output, and can make for a larger and sometime unwieldy file.
</p>
<p id="999238" class="Body">
<a name="999238"> </a>If you are using a commercial printer or a more sophisticated output device, the dimensions of the image should always be set to the actual size it will appear in the printed piece. For the resolution, a good rule of thumb is to set your document's pixels per inch to twice the desired lpi. So, when lpi is 150, the pixels per inch should be twice that, or 300; if the lpi is 85, the pixels per inch should be 170. It's a good idea to check with your service bureau if you have questions about output device resolution.
