Hi there !
?
I am using Richard Boutwell's program QuadToneProfiler-DN v3 to create .quad curve for the gold toned Vandyke Brown process...
?
I am using Bergger COT320 paper and Tecco SF140 transparencies. I am using an EPSON P600 printer.
?
When printing the blocking density test, I found that the blocking density (which is patch 20) is considerably less than the default ink load.
?
?
In this case, the following is adviced by Richard Boutwell :
If you find the blocking density is considerably less than the default ink load (a value of 30, for example) you might not want to lower it too much lower than the default setting because it might make it harder to linearize given that the lower overall ink load is too low throughout the whole scale—especially the mid tones. If this is the case, you should just rely on the linearization function to correct for the increased contrast in the highlights of the print?
?
If I understand correctly, I should move the "Black Boost" slider so that the "Maximum Black Percentage" value that is shown at the top is 20... But even if I drag the slider to the left hand side , the minimum value of the "Maximum Black Percentage" I get is 25...
?
?
What should I do ?
?
Also, I think there are bugs in this dialog.... If I change the process preset in the bottom dropdown, the value of the "Maximum Black Percentage" changes accordingly, also the curves in the graph changes, but the values of the sliders do not change.... This is perturbing, to say the less. (since the curves and Maximum Black Percentage value are derived from the sliders values, right ?)
?
Thank you for your replies and help !

Best regards,
