Printing – Humidity

September 16, 2008 | Leave a Comment |


Extreme humidity can impact print quality. This is particularly true for but not exclusive to matte papers, which are more absorbent.

We printed for my Annual Exhibit in high humidity. The paper had absorbed a lot of moisture and so there was substantially more dot gain. The prints were coming out substantially darker and we were having trouble maintaining shadow detail. It’s made me want to store all of my paper in a climate controlled environment (using a dehumidifier or air conditioner). Or, climate control my entire studio. Rather than reprofiling for an atmospheric condition that changes unpredictably, we compensated with proofing. We lightened the files selectively before printing. With a little testing, we came up with standard adjustments that could be used on multiple images, with customized shadow masks for individual compositions. It pays to think about the impact of humidity on your printing. Control humidity when you can. Compensate for it when you can’t. You get better prints.

What do you do to compensate for excessive dot gain due to environment or overinking? Comment here.
