Ink Choices for Church Offering Envelopes
There are two basic ways ink is used in printing church offering envelopes. Spot color and CMYK color.
Spot Color Printing
Spot color is using a one or two color inks. When using one spot color everything gets printed in that one color. So if the spot color is a red ink, everything is printed in red. Using two spot colors would allow you to highlight text or images in a second color. For example, you can print the headline type in red and the body copy in black or any other two combinations of ink. The advantages of spot color printing are that colors are more accurate to the Pantone color system. Some Pantone colors can be reproduced closely using CMYK and some cannot So spot color printing is best when needing to match a corporate color or a specific Pantone color. Spot color printing can be used with photos, but the photograph will have to be converted to a single color or halftone and then printed with the spot color. This would look like a black and white newspaper photo.
CMYK or Four Color Process Printing
CMYK or more commonly known as four-color process printing is using four colors to achieve full-color printing. The four CMYK colors are cyan, magenta, yellow and black. The mixture of these four colors used by themselves or overlaid on each other, to produce a full-color spectrum. This process is usually used when a church offering envelope uses photographic pictures or graphics in many colors. You would choose CMYK printing when there are color photos or it takes more than 2 colors to reproduce the printed envelopes. CMYK printing is more economical than using 3 or more spot colors. CMYK is the only way to reproduce color photos.
