Testing Colour Accuracy of PDF Files

Adobe Portable Document Format (PDF) is common used for digital exchange. The PDF overcomes several of the limitatations of the PostScript language. A PDF file is designed to be viewed on screen as well as print, and this makes it possible to check the page content before imaging onto hard copy. The aim of this research is to check the reproduction of colors via output systems such as proofers. In experiment differnt inkjet and laser printers were used. Two target tests were printed on different digital output devices. The Altona Measure and Altona Visual Targets contain all neccessary elements for checking compliance and color accuracy and to identify product limitations. Tests are measured with the aim of spectrophotometric and visual judgement.
