I have created a design for a swimming bag where only a blue ink will be used for economical reasons. I don’t know how to save it in illustrator with those blue hues only. If anyone can help me I will greatly appreciate it. (At the moment it has some elements which are colorful)
In the past I’ve saved the file as a pdf then open in photoshop and gave it a “sephia” effect of a color and it’s perfect.
