In Tandem Design, Inc. has a six-color HP Indigo press. Normally, the extra colors are Orange and Violet. With Indichrome screen builds, the added colors allow for better PMS matching, especially with blues. We can also use white ink in one of the extra units. This allows us to print white on clear plastic before printing process color. We can do mock-ups of package designs like clear bags or plastic wraps.
There are many papers for Indigo with pearl, quasi-metallic, and metallic finishes. Printing white ink under process color on those papers masks the reflective finish. This allows for "spot metallics." Pre-press for such effects is not trivial. Please, get us involved from the start if you want to use white ink under process color.
