My local HP Indigo 5500 agent created 39l , 47l profile but my jobs used many kinds of paper such as Antallis paper . When we printed proof on Toccata paper for offset matching. Why I can't use same ink density for both Indigo and offset ? Thank you for recomendations
Density only measures ink thickness, not color. Additionally color is effected by substrate color. I would guess that if you measured your solid ink patches using a spectrophotometer you would find out that the same densities printed on your offset press and your indigo are not close in Lab values, therefore they are not close in color.
ICC profiles, either from Fogra or GRACoL, reference a white point for the substrate. If you paper fits into that general type of paper (gloss coated, dull/matte, uncoated, which effect SID & TVI) and has similar CIE Lab for whiteness (dE<3), then that profile should be close.
I Want to Invest in Inkjet, But…
Over the past few years I’ve watched a group of transactional and direct mail printers strategically shift from monochrome toner machines to full-color toner and inkjet presses. Most banished old black-only toner boxes but kept their color toner devices around because they anticipated needing both color inkjet and toner presses to meet customer needs. They were right then and continue to be right today. Because toner and inkjet can be better together.
