Lately i've used illustrator and didn't understand why any gradient with one colour (100% and 0% opacity) on black background looked so awful and gray. Light part of gradient has been wide but dark part of gradient has been short and between two parts was gray. I try to make gradient fine with more dark colours in black part. This problem i've in Mesh tool if i choose light colour among black, too. Interesting!! If i choose all points on the mesh and make black, then change color one point to cyan , mesh will be awful, but if i change colour black to black for each black points it becoming fine. Unbelievable!!
I try change colour setting but only with "Emulate Adobe Illustrator 6.0" it was working fine. But, anybody, please explain what's going on!!
Not sure what you are trying to achieve. Some screen shots of your file(s) would be helpful. A linear gradient is a lot different than a gradient mesh ( which sounds like you discovered already ). The more you experiment, the more you will learn. Some reading on the subject of gradients might be helpful.
Ок. Simple example on black-white gradient.
How you can see, on majority setting gradient is working not right. But only on one setting "Emulate Adobe Illustrator 6.0" gradient looks fine. It's interesting for me, for what there are many other combination setting? Both my version cs4 and cs6 behaves equally. But photoshop working on "North America General Purpose" and gradients looks great.
What kind of artwork are you doing?
Web or Screen design: use RGB color mode
For anything that will be printed: read up on color management. You'll need it desperately. "Emulate Illustrator 6" will basically let Illustrator do color management in the background using some standard settings that might or might not apply for you. But it won't be up to you to influence it. In case you're not from the US, Illustrators standard settings most probably won't apply for your needs.
Any chance you're speaking German? In that case there is some very good and free information on color management available.
Thanks a lot! Advices Vitalodnepr and Monika Gause is helpful. After how i checked Proof Colour, checked Customize and changed colour mode on sRGB the gradient became more smooth.
But i didn't understand why is Color mode "Monitor RGB" is grayed out. I guessed, that my document has worked on CMYK mode. After i changed on RGB it's working great. Happiness!!
In morning we tried to make fine gradient on RGB mode, and realised CMYK mode sucks and normal gradient can make only RGB. We just change color mode on RGB and gradient became great.
But now I tried to make a normal gradient on CMYK mode, and found something interesting.
Main reason of all trouble with gradient on CMYK mode is default based on grayscale black-white gradient, which we are choosing first of all. We change white color on blue, and notice gradient weird. But Black color on grayscale is that position regulators on CMYK mode:
With that setting we will get gray part on gradient in CMYK mode. But don't get it in RGB mode, because that mode is more independent by grayscale . In my case i just change color mode and was happy. But if we change position regulators like this:
we get correct gradient right in CMYK. I saw similar way on youtube, but guy don't explain why that's happening
Also we can change color mode on RGB and then change back on CMYK. Gradient will become correct, because after converting from RGB to CMYK the regulators will be almost like on last picture.
Thats all! Sorry for my english!)
we get correct gradient right in CMYK.
By no means this will get you correct color in CMYK. Instead this will get you in very big trouble. This will cause the paper to be soaking wet in print and it will cause a lot more trouble if applied to detail because of misregistration.
So to cut the long story short: Don't use this in print.
How i can get correct gradient in CMYK mode if not this way? Only one way is working then, guy tells us on youtube, just add in black color a little tone of other color. But it so strange, because RGB mode doesn't need so much attention. Probably i must learn the color theory.)
Adding a little color to black gives you a rich black, which is sometimes necessary. But in order to determine how much to add and which color exactly, you should talk to the printing vendor, because it depends on the stock used and on the equipment used to print. It also depends on what you want to achieve, because adding a little cyan will give you a rather cold black while adding a little magenta or yellow will make it rather warm and you have to be careful that it won't result in brown.
Probably i must learn the color theory.)
Definitely you must learn it.
