Summary:
Gravure is the major printing process used for publication such as long-run magazine, catalogs, newspaper, and miscellaneous commercial printing. In gravure printing processes, color proofing is for the purpose of checking the color to ensure that it is as desired, before proceeding to cylinder engraving. Recently, the use of inkjet digital proofing gained popularity due to its benefits of high speed, wider color gamut, and affordable prices for a device. Proofing on the actual production stock more closely predicts print outcome. However, paper properties have significant effect on the image reproduction for proofing processes. Working with different inks and devices, the actual production printing substrate can have a very different color gamut and behave differently in the digital proofing process. The color capability of a digital proofing system influences color gamut and performance, which in turn affects accuracy of color for the press to match. This study discusses the color reproduction of digital proofing from the point of view paper properties. Publication printing substrates and manufacturer recommend proofing paper were tested on the Epson Stylus Pro 4000 printer and Xerox Phaser 8550 printer. Paper surface properties (roughness, porosity, pore size, formation) and optical properties (brightness, whiteness, opacity, and gloss) were tested.
