feature request - qtr-print mask function
2013-01-31 by David MacAlpine
Greetings, Thank you for providing QTR-print - it is a fantastic tool and well worth the purchase price. I would like to suggest a feature for use in making digital negatives - a mask function. Typically when using QTR for digital negatives we adjust ink density levels to identify the minimum levels to 'just' achieve paper white. If we try to lay down excess ink to really ensure paper white and complete blocking, it makes linearizing the high tones very difficult (the curve is just too steep in the initial steps). It would be nice to have a mask function in QTR-print that would enable one to specify a border mask of some size (1 inch etc) to surround the image. This border mask would then lay down excess ink (K or Y) to ensure complete blocking of the brush strokes and a nice clean borderless print. The problem is that although we can find the minimum ink levels for paper white in making our original curves, the levels of pt/pd and sensitizer are often quite variable in the border region (ie whispy brush strokes) outside the image. These regions of thin pt/pd and sensitizer are more sensitive to UV and tend to darken faster then the main image. Hence the request for the masking function.
