This new film is capable of increased adhesive capability, resulting in excellent print quality even when printing vivid or deep colours that require high ink duty.The coating of the ClearProof film has been uniquely formulated to give optimal print results with white inks on the SP WT7900, in combination with the Ultrachrome HDR inks C, LC, M, LM, Y, Or, Gr, K.In applications such as packaging proofing, this is a breakthrough technology enabling the proofing industry to provide contract proofs for packaging businesses at a fraction of the cost of previous methods.Whether you print using surface mode, i.e. white first, then all colours, or the reverse mode - printing white as the last colour for reverse viewing (from non printed side) - this 120 thickness polyester film provides the highest accuracy.The product comes in rolls of 17" (432mm) and 24" (610mm) at a length of 100' (30.5m).It's supported by a 30 release liner in order to feed properly through the printer.Like all of Epson's innovative media, this paper is engineered to give you the highest resolution and color saturation possible. This substrate is supported by the established proofing software developers. As always, Epson supplies guarantee Epson quality.
