Coated paper has an agent added to its surface in order to improve brightness, smoothness, or other printing properties. Once coating is applied to the paper, rollers help to “polish” the paper. It fills in the tiny pits and spaces between the fibers, giving it a smooth, flat surface.

What is meant by coated paper?
Coated paper (also known as enamel paper, gloss paper, and slick paper) is paper that has been coated by a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency.
What is coated paper used for?
Due to the vibrancy of the obtained colours, coated paper is typically used for printing magazines and journals, photographs, book covers, catalogues and other promotional materials. When it comes to products by PromoNotes, coated paper is generally used for making covers or promotional cards included in the notebooks.
What is coated paper made of?
Uncoated paper, as the name suggests, is simply left in its raw uncoated state. However, with coated paper, white clay is used to fill the tiny crevices on the surface of the sheet which is then passed through high-pressure rollers to achieve a smooth matt, silk or gloss finish.
What’s the difference between coated and uncoated?
The difference between coated and uncoated paper
Coated paper has a smooth finish, and like a pane of glass, absorbs less ink while being more durable. Uncoated, conversely, has no coating. Generally speaking, uncoated paper is not as smooth, and, like a sponge, soaks up more ink.
How is coated paper made?
Coated papers have a smooth clay coating applied over a freesheet or groundwood base paper. The base paper is made first, then put through a “bath” of clay coating or coated while running on a machine, with a blade and calender rollers smoothing out the coating on the paper.
Who invented coated paper?
Gage, the actual inventor, made it clear that he had invented paper coated on both sides in Massachusetts in late 1874 or early 1875 at the specific request of De Vinne … who needed it for a catalogue with colored wood-engraved illustrations.” (page 114; Tichenor’s book is on Google Books.)
How do you know if a paper is coated?
The textured feel adds character to the paper, and it looks more “traditional” than modern, coated paper. Color may appear darker on uncoated paper than on coated, and images are less sharp. More ink is absorbed by uncoated paper, which may cause images to appear fuzzy, and the edges of images may appear less defined.
Can you write on coated paper?
Coated paper can be very shiny or have only a subtle shine depending on the choice of finish. The coating on many coated papers means you can’t write on it with an ink pen, so don’t choose it for forms that need to be filled out—use uncoated paper instead.
What is the difference between printing and coating?
In case of printing procedures, the application roller is in contact with the substrate. During coating procedures the process can be contact- less or with contact.
Is coated paper better than plastic?
Paper is far more biodegradable than plastic and very easily recycled. But it often ends up in landfill, where its degradation rate slows – while it takes up more space than the same weight of plastic.
Why is uncoated paper more expensive than coated?
Why is that? A key reason is that wood fiber is one of the most expensive components of paper, and uncoated papers require a higher ratio of fiber per pound than coated sheets.
Is coated paper shiny?
A paper does not have to be “glossy” to be considered coated. Coated paper has an agent added to its surface in order to improve brightness, smoothness, or other printing properties. Once coating is applied to the paper, rollers help to “polish” the paper.

In the world of commercial print, the overwhelming majority of print projects are produced on either coated or uncoated paper. Each type of paper has its pros and cons relative to the project. And printers will typically have a preferred or “house” stock available in both types to accommodate numerous projects.

What is coated matte paper?
Matte — a matte coated paper is a non-glossy, flat looking paper with very little sheen. These papers are more opaque, contain greater bulk, and are higher in cost. Matte coating prevents the ink from absorbing into the paper. Dull — a dull finish coated paper is a smooth surface paper that is low in gloss.
What is uncoated paper made of?
Woodfree uncoated paper (WFU), uncoated woodfree paper (UWF) or uncoated fine papers are manufactured using wood that has been processed into a chemical pulp that removes the lignin from the wood fibers and may also contain 5–25% fillers.
Which chemical is present in paper?
Chemicals used in paper manufacturing
| Common name | Scientific name | Notes |
|---|---|---|
| Albarine | “Calcium sulfate” | Building materials |
| Chlorine dioxide | Chlorine dioxide | Pulp bleaching |
| Chlorine | Chlorine | Pulp bleaching |
| Dolomite | Calcium magnesium carbonate | Filler, Coating |
Is clay coated paper recyclable?
For many glossy papers, the additives are natural, which is fine clay. In the recycling process, recycling companies only need to employ a unique method to wash off the clay. This way, the papers would become fit to be recycled.
What makes paper shiny?
For decades, glossy paper, the type used in magazines, was made using a white clay called kaolin (named after the Chinese region Kao-Ling where it was mined to produce porcelain). The clay is used to fill the spaces between the fibers in the paper and to coat the paper so that it will have a smooth surface.
