1. Now, finally, we’re getting to the coloring part of the series of tutorials! This is a pretty basic part. Open your inks file.
11. Select the “Zoom Tool” (magnifying glass) and select the first area you want to color. You can select a specific area of your art piece by clicking, holding down, and dragging over that area with the magnifying glass. In this case, I am selecting the girl’s hair to color first, so I have selected her head.
13. Now start selecting the area you want to color. I would suggest selecting from within the outlines so that the colors extend out beneath the edges of the art. This reduces the likelihood of missed space in the coloring. When you connect the original point where you started the selection with the end of your selection, your selection with generate.
21. In the options box that pops up, name the file “YourFilename_FINAL_PRINT” (This is to indicate that this file is optimized for printing. It is a large file at this point, so I wouldn’t try and use it for anything else.) Click “Select File Type” and choose “.jpeg” and then click export.
23. In the scale image options box, within the width field, choose a number under 1000 (which represents pixels) and then hit tab on your keyboard and the height should change as well. Now go to the “X Resolution” and change the number from “600” to “100” and click tab again, the Y resolution should change. Then click scale.
24. Using the handy dandy, “Save for Web” plugin for GIMP, I am going to now save my file so that it works for web sharing faster and easier. (You will need this plugin for that step, so if you don’t have it installed, take a minute to do so now)
25. In the “Save for Web” options box make sure the “jpeg” setting is selected. Adjust the “Quality” and “Smoothing” options keeping an eye on the “File Size” indicator. (It should be under 100kb for web use) then click “Save”
26. Within the “Save image” options box, name the file something like “filename_final_forweb.jpg” to indicate it is for web usage. Then click save.
27. Now you can click out of GIMP. Don’t save anything at this point because the scaled image might accidentally override the settings on your large print file.
