General Commercial Printing Guidelines
Commercial printing and offset lithography
printing has always been and still remains a highly technical process.
Unfortunately, few graphic designers today have the knowledge, experience, or training to produce files that result in perfect printing quality.
Poor print quality is almost always the fault of a graphic designer with little or no knowledge of 'pre-press' and the steps needed to insure best print quality.
Commercial printing remains a 'garbage in garbage out' type of process, where the quality of the printing completely relies on the quality of the original files, and the technical quality of the digital printing files made from the original files.
Commercial printing is not inkjet. Therefore, printing out a file in a program such as Adobe Photoshop, Microsoft Word, Microsoft Publisher, Abode Illustrator, or other software to an inkjet printer without any 'printing press' simulation will not produce an accurate result.
The basic rules:
In offset lithography, there are four printing colors known as 'process' colors.
The process colors are Cyan, Magenta, Yellow and Black.
