![]() ![]() Most laptops have 6 bit per channel displays with some animated dithering tricks to make things appear better. Image scaling will ruin the good work dithering has done, so you'll need to create the image at the correct size from the outset. It's 8 bit per channel and doesn't dither. (See previous point.)ĭon't use Illustrator. ![]() If you want an all solid gradient created from one layer, 8 bit per channel is ok (16 bit is only handy when there's layer blending involved).ĭithering is really, really important. The best quality way to generate a gradient that's created from several layers (with blending modes and opacity at play) is to render at a higher bit depth, then dither down to 8 bit per channel, if possible. There can be some cumulative rounding errors if your image editor is using 8 bit per channel colour depth. Edit: Photoshop CC 2014.2 added alpha channel dithering. Create the gradient using the exact colours you need. You're better using solid colours, if possible. Photoshop doesn't and can't dither on the alpha channel. There's lots of factors to take into consideration though. Yes, it's possible to create high quality gradients. It also makes difference then wether you use raster graphics or vector graphics.īottom line is: this is quite complex subject :). There's a difference how much you can “spread” your gradient whether you're targeting print (what kind of print also matters e.g.: screens like AM, pseudo-stochastic, stochastic) computer monitors or mobile devices displays. too “agressive” monitor profile (again view-on-other-monitors test should provide some hints about it),Īlso it would be useful to know what your target device is.in “video card control panel” or gamme loader like Adobe Gamma Loader), “wild” video card gamma settings (e.g.reduced “per-channel” color resolution in system settings (seems unlikely nowadays since most systems use 32 bps settings, but still a possibility),.miscallibrated/poor quality monitor (have you tried to view your gradients on different monitors?),.“stop” points are getting farther from each other-gradient have to be “projected” on more samples with the constant number of available brightness values), gradient size (banding becomes more apparent when “start” and.There's a couple of things that may make “banding” more apparent: Noise and dither usually yield quite good results. ![]()
