When you’re looking for a coated postcard as solid and reliable as you, this 18 point postcard option is the reigning heavy weight champion.

How Small Can Text Be on 18pt Coated Cards?

The minimum recommended text size is 6pt. With any small text, if grey use a black ink only version; if black, use 100% K.

Can I Use Thin Lines on Indigo Printed Cards?

Anything thinner than a hairline stroke (0.25") - even at 100% K may look choppy when printed due to Indigo print resolution.

Is Indigo Resolution Different From Offset?

There is a screen to the Indigo print which customers should be aware of if they're comparing to traditional offset printing.

Should You Use Rich Black on Indigo Cards?

Don't use rich black on Indigo printing. 100% K will be just fine.

Can I Round Corners on Indigo Cards with Heavy Coverage?

Heavy ink coverage can be problematic. When the cards rub together, the ink can rub off. This can be an issue for corner rounding so we generally advise clients with heavy coverage not to round corners.

Can I Write on 18pt Coated Cards?

Coated cards aren't ideal for writing on. If this is a big deal, check out our uncoated card stock options.

Can Greys Shift?

CMYK Process colors in the grey range and de-saturated images can shift in color throughout the print run and may cause the greys to appear either cooler or warmer. For a neutral grey, we recommend converting all grey values and de-saturated images to true greyscale consisting of K (black) only values.

Is There Color Variation on Solid Blue?

Depending on the color value, you may experience color variation in solid fills of blue. For great blue results, we recommend a 30% difference between your Cyan and Magenta levels to ensure a nice rich dark blue, rather than purple.
