We often have people ask the question “What’s the difference between coated and uncoated paper?” Today, we’re going to explore the differences in how the paper is made, and what they both can be used for!
How is Coated Paper Made?
Coated papers typically have a compound (generally clay) applied to their surface so that the pores are “sealed.” This limits the ink that is actually absorbed into the paper. It also allows the ink to sit on top of the paper in a much crisper dot that is more well defined.
The basic difference between coated and uncoated paper is the fact that one has a substance that fills the gaps between the individual paper fibers, and the other does not. Coated paper has an agent applied to the surface of the paper in order to improve the different properties of the paper. Some of these properties include brightness, smoothness, and others. One common misconception is that coated paper needs to be glossy, and that is not the case. There are many paper types that are coated, with more of a matte look.
Pros and Cons of Coated vs Uncoated Paper
Each type of paper has its advantages and disadvantages depending on the type of job you’re completing. Most printing companies typically have preferred suppliers, and product lines in each category of paper to accommodate different project types from local businesses.
Uncoated white papers are graded by their brightness levels. The brightness level is a percentage breakdown of the amount of light that is reflected back toward the viewer. For example, a 98 Bright Rating would be indicated that 98% of the light is reflected back to the viewer. This is an important indicator when dealing with CMYK vs RBG color models since the brightness of the white will directly correlate to how much your CMYK colors “pop” off of the page.
Coated papers on the other hand are categorized by their finish first and then will use brightness as a secondary qualifier. There are premium Numbers 1-5. A coated paper with a brightness of 88+ is classified as a premium and as a coated paper – the glossier the finish the less ink absorption.
What’s the Difference Between Coated and Uncoated Paper when it comes to budget?
When attempting to make a budgetary decision on coated vs uncoated paper, be sure to consider things like the caliper and opacity of the product. Ask your printer about the potential of utilizing a lighter-weight, uncoated sheet vs. a heavier-coated sheet that is coated.
For example, if you are quoting a project that is utilizing an 80lb. coated paper, there is the potential that a lighter weight uncoated paper will likely be able to match the opacity and caliper resulting in you using and paying for less paper. The decreased weight could also save you money in logistics costs during transport.
Since both types of paper have a diverse set of capabilities, the budget shouldn’t be the only factor that you consider when making the decision on which type you use.
