How to combine (merge) multiple swatches / fills / patterns in Adobe Illustrator CC CS6 CS5 etc tutorial via styles. Illustrator swatches are wonderful designs on their own, but combining Illustrator swatches (AI format files) they become even more magical. Combining multiple swatches in Illustrator can result in subtle designs with a lovely painted Illustrator look or perhaps more extreme like the image on the right which uses blending modes and mixes two diamond Illustrator swatches or perhaps use gradients in combination to create even more amazing gradient swatch designs. Note: there is a merge Illustrator swatch feature but this may or may not work (it does not work with my version of Illustrator CC 2017 but it should work with earlier). This tutorial shows you how to combine the swatches / merging them via the appearance panel in Illustrator. This tutorial also shows how to combine Illustrator swacthes if transparency is included and how to save the swatches combination as an Illustrator style.
You can go to the right side menu of appearance panel and clear appearance to get to a decent start point.
Go to the swatches panel and select an item (can be any of the ones on the site or any other sets).
Once you have applied one fill
Then go to add new fill or duplicate command (same menu as before) and add a swatch.
You will only see that one now as the lower down fill is hidden by the top artwork (in most cases unless there is transparency).
Go to the opacity section (it is displayed as a link next to the fill in the appearance panel) on the latest fill and set the opacity to say, 50%.
Or set the blending mode to darken or lighten etc and depending on the fills, more or less of the underlying fill will be seen.
Some of the tiles in the various sets do not need to use the opacity / blending mode. Some of the swatches tiles already have transparency inbuilt and can be combined multiple times without the need to change the opacity etc. You can also shift / move the artwork in the swatch (or scale or rotate) via the object menu transform (the key thing is to set the transform object option to OFF and put the pattern to ON) I must admit the move command / panel is terrible to use - certain they could make it a little more flexible and perhaps interactive to use.
select the swatch fill line in the appearance panel
go to the object / transform / move command
deselect the object option
enter the settings to shift the pattern (as with the image on the left made up of two swatches - basically the same swatch but modified to be blue instead of an orange Illustrator swatch)
Once you have added all the fills and strokes
go to the graphic style's panel
select the right side menu
select the new style option and save all the combinations into the style's panel
You can now re-use the merging / combination of the two swatches (or three or four swatches etc)
At the present, the Illustrator merge functionality makes no sense (not in my version of Illustrator). It does not seem to merge gradient or patterns. Perhaps that is not the purpose of the merge but it does seem a little limited if that is the case. Anyway, the merge swatches function is there and perhaps you will have more joy with it in CS5 (when it used to work)
select two or more swatches in the swatches panel
Go to the right side menu
Good luck, perhaps you will be ok and the swatches will merge fine using that approach
They Illustrator swatches are all seamless tiles. They come in a variety of colors and artworks - see more via the Illustrator swatches but how to combine them, how to blend them into something even more super colorful and amazing for use in your projects. You can also find more swatches such as zoom swatches and triangle swatches and starburst swatches
You can find many other tutorials such as how to open and load the Illustrator swatches
