1A higher L* than 1B, what to do..?

2007-12-22 by oisteinthomassen

Hi,

I am using an Epson 2100 with Lyson CavePaint (PhotoChrome) CIS. When 
printing the target on glossy papers, e.g. the new Ilford Gold Fiber 
Silk (baryta) and Innova Fiba Gloss, the 1A patch comes out brighter 
(L=6,9) than the 1B patch (L=5,8). This is after a couple of rounds 
with hahnemuhle protective spray (before spraying, the 1A patch is 
considerably brighter than 1B! almost grayish). Could this make 
problems for the profiling process? I often have problems with shadow 
details, and one solution for this has been to open up the levels 
output slider in Photoshop (e.g. from 0 to somewhere between 10 and 
20). Thanks in advance for any comments.
