Requirements for vector formats
Zoom Image 1: 1. All fonts in vector files formats have to be translating into curves.
Color reproduction.
Do not focus on the image on the monitor or mock trial printing on color printers, if the special attention has to be payed to color ( “hit” in the corporate color palette with color emulation Pantone, print reproductions of works of art, etc.). In this case, the only 100% guarantee against mistakes – is a proof, made on the same equipment and materials as the main printing order.
Color try might be :
- scale – thumbnail assessment for color reproduction on a large widescreen product ;
- natural – fragment in 1: 1 scale for assessing color reproduction of parts of large size products in bulk;
- range of colors – color output samples ( “squares”) with a certain color range for selecting desired color (color tone).
Approved by customer color try is the only reason for receiving complaints on the quality of color
In case of discrepancy of given to print files and materials with the above requirements, they must be agreed with the manager.
