58 Corel Painter X3 Getting Started Guide
To create a custom canvas preset
1 Choose File New.
2 Choose the settings that you want to save as a canvas preset.
3 Click the Add button .
4 In the Add Preset dialog box, type a name in the Preset Name text box.
A custom canvas preset is not a template. Unlike a template, it does not allow
you to store any content. A custom canvas preset allows you to store only
canvas dimensions, resolution, color, and texture.
You can delete a canvas preset by choosing the preset name from the Canvas
Preset list box and clicking the Delete button .
Understanding resolution
When you work with images in a digital workspace, it is helpful to understand the
concept and applications of resolution. Resolution refers to how Corel Painter measures,
displays, saves, and prints images — whether as small squares of color called “pixels” or
as mathematical objects called “vectors.”
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,
save, or export a file.
Resolution and screen appearance
Most monitors have a resolution of 72 pixels-per-inch (ppi). The Corel Painter display
default is 72 ppi, which 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
number of pixels-per-inch — it affects only how the image is displayed on the monitor.
For example, a 300-ppi image is displayed on-screen at approximately four times its
actual size. Because each pixel in the Corel Painter image occupies one pixel on your
monitor, and the monitor’s pixels are approximately four times the size of the image’s
pixels (72 ppi versus 330 ppi), the image must appear four times larger on-screen in
order to display all of the pixels. In other words, your 300-ppi document will be printed
at approximately one-quarter of its on-screen size. To view the image at its actual size,
you can set the zoom level to 25%.
