Star Proof - Packaging features
Star Proof incorporates a number of features which have been specifically developed with the Packaging sector in mind, with the aim of producing a proof which replicates the final printed job. These features include a Dot lost function whereby users have the ability to remove highlight dots from the inkjet proof to mimic the result of the flexo plate development process and an Extreme Dot Gain feature which shows the result of the halo effect found for example when printing with thicker Flexo substrates on corrugated stock.
Additionally, users can change the Sequence of colour on CMYK and Special colours such as Pantone or Opaltone, show the effect of Misregistration to ensure trapping parameters are correct and, using the Multi colour shade calibration system, calibrate and produce a spot colour report.
White Ink and Multi-substrate support
The latest release of the Epson Stylus Pro WT7900 brings a new generation of flexographic and Gravure proofing with Multi substrate support and a new aquaeous based white ink.
Star Proof supports the WT7900 in both reverse and surface printing modes; the former for transparent materials such as Clear, Shrink Wrap and Adhesive film, with the latter being used in instances of opaque substrates such as Metallic medias.

Multi Color Shade
Matching special colors on a digital proof is challenging, mainly due to the color gamut limitations of inkjet printers and the capabilities of color management software.
Now, the Epson Ultra-Chrome HDR™ Ink utilizes ten colors, including an orange and green producing a far wider color gamut.
Star Proof takes advantage of this technology via Multi Color Shade to match to any standard color library. Mixing special colours, even those including white inks is simple and intuitive

Misregistration
Developed to help avoid potential problems on press, the misregistration feature simulates the effect of press misregistration for each separation, a function which allows users to check if the applied trapping distance covers the press tolerance.

Dot Lost
A Dot lost function automatically removes highlight dots from the ripped 1 Bit Tiffs or Barco Len files prior to proofing. The resultant proof shows the effect of lost dots caused by the processing of the Flexo plate and delivers a proof which is both data integral and indicative of how the job will look on press. |
Extreme Dot Gain
The Extreme Dot Gain feature in Star Proof has been developed to simulate the effect that plate pressure can have on the printing process. Certain substrates such as corrugated materials require deeper shoulders or cells on the Flexo plate which can result in a "halo" effect being produced on the printed job. Star Proof is able to simulate the effect of this Extreme Dot Gain by adding pixels to the Raster file, again, ensuring that the proof simulates the final printed copy. |
