We have sophisticated trapping software to properly trap all jobs, free of charge. If you have special reasons to apply your own traps, please contact us first. Process vs. Spot Color You must specify all colors to print with the proper inks. If your print job calls for black ink and a PMS, that PMS color cannot be electronically defined as using process inks. The same applies to process jobs, the colors cannot be defined as spot inks.
Most applications allow both spot and process color definition.
Do not confuse type of ink with model. A color can be defined using the Pantone Matching System as the model and the type as Process. This produces a 4 color process simulation of the PMS Spot color selected. To be sure you have defined all colors properly, print separations on your laser printer and check that all the color elements are on the right plate and that they are screened properly. The DPI of a given image is one of the key factors in determining the final output size of the image and how well the image will reproduce.
