gamut warning

gonnadeleteblog-deactivated2014  asked:

Hello! I just wondering about your prints, doesn't it have to be CMYK in order for the colours to be shown well? If you work only in SAI (which doesn't support CMYK), how does the colour of your prints turn out well? Do you edit it in Photoshop, if so, how? Sorry if this has been asked before, and thank you for reading!

Heyo! Sorry for this belated response. Cmyk printing is something I’m still trying to figure it out myself so I can only give tips from personal experience. Yes, I only work in SAI and it doesn’t support CMYK unfortunately. I always edit in Photoshop afterwards. What you can do it ideally test print your images at home with your own printer or there are some online printing companies that allow you to order actual hard copy proofs of your images so you can edit accordingly which is super helpful!

In Photoshop (I’m using Photoshop CS6), there are several ways to do this. One method is to covert image to CMYK mode under Image > Mode > CMYK Color. This usually merges all your layers though.

Another is if you’re working in RGB profile you can go under View > Proof colors. This sets the profile you want to simulate or test with overriding normal display color management so basically it’s showing you the CMYK colors as it would print on paper. Not super exact but gives you an idea. It appears duller than RGB profile. 

You can edit your colors as and keep checking the Proof Colors option on and off to try to get it to how you like.

Something to keep in mind while you’re working with cmyk printing is the gamut colors. Gamut is basically the range of colors that a color system can display or print. Most RGB colors are too vibrant, thus out-of-gamut, and are unprintable. 

You can see which color won’t print under View > Gamut Warning. Click and Unclick to see which colors are out of range.

You can also color pick a color in your drawing, open up the color picker and it should give you this warning icon that shows you it is out of range. Clicking on it will give you the CMYK substitute which is usually much duller. In regards to my illustration, the bright blue color of the sky will be replaced automatically with a color replaced within the CMYK scale if it prints.

Clicking View > Gamut Warning while in color picker, shows you exactly where the printable color range is (image below). So in regards to the blue sky of my sousuke drawing, that color will not print.

OH Another thing… my colleague gave me some tips with Color Settings when I printed out assignments for school. In Photoshop, go to Edit > Color Settings and select Adobe RGB (1998) for RGB. It provides a larger gamut range for RGB which helps when you’re converting to CMYK! And it prints fairly true to what I see on my screen! YAhoo!!!

Adjusting colors is complicated and it takes some experience to get right! T_T GOOD LUCK! I hope this was somewhat helpful! There are way more helpful links and explanations online too so yeah don’t…take my word on it because I’m still learning myself…. Eep. 

IMPORTANT update on CMYK and RGB for Photoshop.

Dear fellow artists, Armellin’s here to tell you some news on CMYK and RGB.

I am sorry I didn’t do it earlier, but I’ve made a call to a relative of mine who’s working with printing companies and preparing files for being printed in CMYK, and that’s what he’ve told me.

If you don’t know how to draw in CMYK in PS properly, don’t do it! 

Draw in RGB scheme, using 8!!!!!!!! bit colours (you can set back to it easily).

Check your work from time to time with the Proof Colours function. You can find it in VIEW or just use ctrl+y. This will show you your picture in CMYK, don’t forget to turn it off after you check it.

Sometimes check you RGB art with Gamut Warning which also can be find in VIEW or by using ctrl+shift+y. It will show you if you have colours on your artwork which will be LOST or GAMAGED while converting from RGB to CMYK.

So you work in RGB and check for CMYK preview. And you will be fine.

***

Please be aware that even after you have completed your piece you may still be required to make some adjustments or fixes to the artwork due to the conversion process if you are unable and ask us to convert your artwork. If you start working using the method listed above then you shouldn’t have this problem but if you have to convert after you have finished the piece then it may cause some issues.

Info below is not that important for the book, but is important for artists posting online =)

There’s a colour schemes set up on ctrl+shift+k, there’s and RGB colour schemes that could be chosen. Chose the one called sRGB IEC61966-2.1 if you are planning to post your art online or work with it online in any way. It’s more simple then AdobbeRGB, but it’s more unified for all monitors everywhere. After that if you will open up you artwork in PS it will ask you if you want to CONVERT colour scheme to a new one. And if you say YES you’d see it a bit different(may be) but much closer to the way EVERYONE will see it online.

Hi :) do you have a solution to the issue of not knowing if your screen colour settings will match the print output settings of the place that prints your comic???? really enjoying the new pages by the way! Seta :'(

One good way is to use Photoshop’s “Proof Colors” function: View > Proof Colors, and be sure that “Working CMYK” is selected under View > Proof Setup.

While it’s difficult to know how each printer will handle your image, they’ll all be printing them out in CMYK. With Proof Colors, you can work in RGB (lower file size, more filters/blending-modes available), while making sure that the colors you pick will look okay when converted to CMYK.

Additionally (this is my favorite option) you can check View > Gamut Warning and it will show colors that don’t print well in CYMK as solid gray pixels.

You can then make a selection and adjust the colors until they don’t appear gray anymore (Image > Adjustments > Replace Color… works well for this.)

A good thing to remember is that images will always print out darker than they appear on your screen, so always make sure to keep at least your focus elements relatively bright. You can use color contrasts rather than luminance differences to imply dark vs light in the scene (admittedly something I often neglect XD)

Lastly, even if you’ve taken tons of precautions, the only foolproof way to make sure the print comes out the way you want it is to order a single test copy and see if anything needs major revisions before getting more printed.

I hope this helps!
