What is a rich black and how do I make it?
Rich black is the name of the color made up from cyan, magenta, yellow and black inks to create a deep black for four color printing. A rich black can be used for large solid areas of black or just an area you would like that extra dark color. We strongly recommend a mixture of 30% C, 30% M, 30% Y & 100% K. To make that mixture, simply go into the color palette of the application you are using. Create a new color with the values above. That mixture will achieve the deepest black color. Using 100% of each color will cause inking problems during the printing process.

What size envelope do I need for a 6 x 4 invitation?
The closest size envelope would be an A-6 which is
4 3/4\" x 6 1/2.\" If possible you may want to make your invitation an quarter inch smaller than the envelope (in this case 4 1/2\" x 6 1/4\") for a nice fit.
