Dear collegues, In order to prepare an unbiased quality assessment I would like to propose the following: Please let me know if you ... … would prefer another approach. … would like to change the assessment criteria: Procedure ---------------------- (1) Sascha Bugai will send printed samples to all working group members who expressed to participate in the evaluation. these samples include different inking versions: ISO compliant, higher/lower Black density, disbalanced CMY (2) I will prepare an Excel sheet with the following criteria (see below) (3) Each member's feedback will be collected *anonymously* (4) Per profile version (A, B, C, D) we will fill in the respective rating per criterion rating with points (0-5) where 0 points means bad result - 5 points: excellent (5) Excel sheets sent back to me (6) Overview with the collected *anonymous* results sent via our mailing list like Version A: x of z possible points, B: y of z possible points Assessment criteria --------------------------- (1) Details/definition (Zeichnung/Kontrast) details reproduced with good definition (5 points) vs. flat detail reproduction (0 points) (2) Smooth gradients (glatte Verläufe) smooth gradients (5 points) vs. distinct posterization effects (0 points) (3) *Gray balance* (Graubalance/Farbstabilität) will be assessed in the print samples with different inking (higher/lower black density, disbalanced CMY) 0 points: gray with distinct color cast 5 points: almost no color cast (4) *Color stability* (Farberhalt/Vergrauung) Unchanged color vs. e.g. less saturation/grayish colors heavy GCR at least in the past caused problems like 'gray islands', sudden shift to gray in gradients of dark colors 0 points: image colors changed (e.g. grayish) 5 points: image colors almost unchanged (5) Reproduction of highly saturated colors (Gesättigte Farben/ Differenzierung) This criterion reflects the rising importance of digital camera data with highly saturated colors (blue tent 'Otto' image) 0 points: flat detail reproduction/ definition 5 points: excellent detail reproduction with clearly reproduced colors/details Best regards, Florian Suessl -- Florian Suessl, Director Technology MetaDesign AG, Leibnizstrasse 65, 10629 Berlin +49 30 59 00 54 246, fax +49 30 59 00 54 114 fsuessl(a)metadesign.de, http://www.metadesign.de, http://www.metaprintcheck.de
