ENWW 27
Glass
Considerations
• The smooth, non-porous surface of glass does not provide a good interface for ink to
adhere making it susceptible to scratches and scraping. Special precautions are necessary
in the handling and display of the the printed piece to protect it from abrasion.
• Adhesion can be improved with the use of a pre-treatment or primer, such as HP PT40
Specialty Glass Scitex Primer – part number CD571A.
Preparation
• Use a lint-free cloth with a glass cleaner to remove dust or debris. Do not use a detergent.
• Use clean, cotton gloves to avoid fingerprints.
• If a pre-treatment primer is used, apply it according to the instructions and allow it to dry
before printing.
Recommended print modes
• Photo Plus profile for applications that will be viewed from the printed surface. For
increased saturation, use Photo – Saturated or Photo Plus – Saturated.
• Indoor Signage Plus or higher quality for applications that will be viewed through the
glass and either a white ink overflood is used or white backer is applied over the printed
surface. Flip the image in the RIP software prior to printing for view-through applications.
• Photo – Backlit or Photo Plus – Backlit, using either Spot or Overflood modes, for backlit
applications.
Printing
• Select Clear Sheet when configuring and loading these media.
• Media placement detection is disabled when using these media. When loading the media,
it is necessary to enter the location of the left (user side) and right (service side) edges of
the media according to the Media Measurement Option selection.
• Use a Clear Sheet media profile from the RIP software.
• For applications that require fine detail, use the Fine Text option and/or lower the
printhead height from its nominal 0.085 inch (2.2 mm) setting.
Output handling
• Use clean, cotton gloves to avoid fingerprints.
• Take care when loading or lifting sheets off the table as media and ink can be easily
scratched.
• Depending on the end use application, a post treatment may be necessary to minimize
risk of surface damage.
