White Ink and Layer Order for Printing on Glass
Compare front-view and through-glass printing using layer-order samples and controlled visual inspection.
Decide where the viewer stands
Draw the glass, printed face and viewing direction on the artwork brief. A reverse-view graphic may need mirrored artwork and a different white-and-color sequence from a front-view design. Confirm the printer and RIP support the required stack before preparing production files.
Make a comparison strip
Print representative light and dark colors, fine text and a solid white region using the approved layer configurations. Label the layer order on each coupon. Inspect from the intended side under the installation lighting and compare opacity, registration and color against the approved proof.
Approve both appearance and adhesion
Check that edges and details remain acceptable after the specified conditioning and adhesion test. Keep ink, primer, artwork revision and viewing direction with the signed sample. If the client changes the viewing side or glass coating, run a new proof rather than assuming the existing profile will transfer.
What to record before production release
Print readable orientation marks on the trial proof and label the viewing side outside the artwork area. Keep a physical approved proof; a monitor cannot show actual white opacity through the selected glass and its coating.
