Uncoated stocks have a porous surface, which absorbs ink and can make colors appear more dull and not as crisp.
If you think about it in simple terms, coated stocks are like a pane of smooth glass and uncoated stocks are like a sponge. Ink will sit nicely on top of a coated (glass) stock surface, giving a bright and colorful, clean crisp output. In contrast, uncoated stocks will absorb some ink (like a sponge) causing colors to appear more dull and less vibrant; even not as sharp.
Print settings are optimized and calibrated for each type of stock to give the best output; however, this effect is a property of the paper. Many designers will add more saturation to colors when designing for an uncoated stock due to this effect. Others will create their designs with this "inconsistent" look as a desired effect, as it does tend to make the print feel more rustic, or handmade.
The use of heavy coverage or full color backgrounds is not suitable for this stock. Minimalistic designs are best! If your design has a lot of color and heavy coverage, we suggest a white and coated stock for optimal results.
One side of the Bamboo stock is slightly rougher / more textured than the other, meaning designs and colors may appear slightly different from back to front.
Due to the slight texture of this stock, it cannot hold fine detail as well. The finest detail we recommend is 1pt line-weight; however, please note that light colors or lines that are not solid (such as dotted lines) should be made thicker.
