Convert Color to Grayscale in Adobe Photoshop
For the best results, you should always work from a duplicate file. Illustrator preserves editing capabilities but to keep yourself organized, it’s in best practice to save a separate grayscale IC print file.
» Open your file in Illustrator
» Select all of the objects whose colors you want to convert.
To select all objects in a file, choose
Select > All. (To deselect all objects, choose Select > Deselect)
» Don’t forget to unlock all layers & objects on your artboard!
Object > Unlock All
» Choose Edit > Edit Colors > Convert To Grayscale
NOTE: Use the Edit > Edit Colors> Adjust Colors command to convert objects to grayscale and adjust the shades of gray at the same time.
Your Illustrator file is now ready to save as a PDF file! Happy printing 🙂
