Indeed, when deciding on print size of your image, you must choose a size that is appropriate to resolution of image you are supplying. The size to which your image can be printed without a loss in quality depends on resolution of your image. Remember that higher resolution of your image is, better quality of image when printed.

Most digital cameras allow you to select a combination of resolution and quality from settings menu. In order to obtain an optimal print out, you must set your digital camera at highest possible resolution and quality. Always remember that higher quality, larger image file will become. So folks, make sure you have sufficient room on memory card!

Graphics files are best printed in CMYK mode. CMYK is referred to as standard color model, or four process color, used in offset printing.

Why do we use CMYK color model? We use this type of mode because it produces greatest number of printable colors. But it is not applicable to all types of printing, particularly when only a single color is needed and when spot inks, such as metallic silver and gold, are used.

All display devices, such as your computer monitor, use RGB (red, green, and blue) mode. CMYK is based on printing and ink absorbing into paper. Before you can have your graphics printed in CMYK mode, you must first convert RGB colors into CMYK colors. This is done through color matching. Color matching is process in which colors are used to produce another color without altering original color. You can also convert colors using Adobe Photoshop or a desktop printer. In converting colors during printing you must have different sheets of film for each color. The sheets must be arranged in CMYK format.
