6. Clear resin barrier layer
• Extrusion coated, clear polyolefin layer
• Allows backprint to show through
• Prevents water from absorbing into the back side of the base paper
• Provides a balanced base sheet
Layers 5-7 comprise what is commonly referred to as RC (Resin Coated) photo paper.
These 3 layers control the core optical and physical properties of the product – the so-
called look and feel of a photograph. The physical quality of both the base paper itself,
along with the precision resin coatings and anti-stat, define the term “true photo paper.”
Cheaper alternatives, dubbed “faux” photobase or sometimes “barrier-coated” base paper,
start with lower quality base paper and/or use a solution-coated water-barrier layer.
Inkjet papers coated on these cheaper alternatives are easily differentiable from true
photo papers in terms of their poorer surface smoothness, less bright and white
appearance, and coarser and less uniform paper formation.
7. Antistat layer
• A very thin coating of proprietary antistatic material
• Prevents charge build-up (static cling) during coating and printing
• Improves transport of the paper through the printer across the temperature and
humidity range specified by the printer manufacturer.
8. Curl control layer
• Used to balance the natural curl imparted by the ink-receptive formulations to
maintain a flat final picture
• Comprised of a swellable polymer similar to that used in the ink-absorbing base layer
9. Wet stacking layer
• Thinner, ink resistant layer coated over the curl control layer
• Crosslinked polymer with matte particles to give it a textured surface
• Prevents prints from sticking together when making multiple prints unattended
Layers 7-9 complete the package, providing easy, reliable printing of your favorite digital
photos on KODAK Ultima Picture Paper in any desktop inkjet printer.
Universal Compatibility
Excellent image quality can be obtained on all major brands and models of photo-capable
desktop inkjet printers. The new KODAK Ultima Picture Paper with COLORLAST
technology has been and continues to be, tested on hundreds of inkjet printers. Each pack
of paper comes with an instruction sheet that shows consumers how to optimize their
specific printer driver settings to create high quality, pleasing pictures. To make it even
easier, only Kodak provides consumers with literally “one touch” ease of use to create
even higher quality pictures. The One Touch to Better Pictures feature with KODAK
Easy Share software automatically chooses the appropriate driver setting and
incorporates Kodak Color Science into each and every inkjet print. The result is
