Printing on to Different Types of Paper Stock

Firstly you need to be aware that paper is either coated or uncoated.Uncoated PaperStandard uncoated paper is a commonly used paper for printing, found in paperback novels and newspapers. When printing the uncoated paper soaks up the ink like a sponge. Ink enters the paper fibres and spreads, causing dots to occur. This is particularly obvious in newspaper print. Photo quality can suffer due to these dots occurring but for inexpensive newspaper or novel prints with few images, standard uncoated paper is an acceptable choice.Premium uncoated stock has a smoother surface due to the addition of chemical additives, so the ink is better able to sit on the surface. This occurrence is called ink holdout. The dots printed on to the paper spread out less, meaning a crisper print. There still can be bleeding of ink (HYPERLINK) in this type of paper. Therefore less ink should be used. Coated PaperThis type of paper has a surface sealant, much similar to a varnish on wood. This coating allows air swimmers the ink to sit on the surface of the paper without seeping into the paper fibres. This makes the ink easy to control and therefore the printing is sharp. Though to gain this crisper look you are likely to have to spend more money.Under the title coated stock there are many options on look of the paper: matte, dull, satin and gloss. All these options allow for variance in the shine and sheen of the paper, the most commonly used are matte and Motorcycle Gloves gloss papers. Gloss papers are super smooth, reflecting light rays to showcase a range of colour tones from light to dark in an image. For example you may use this type of paper to highlight the metallic lustre of a car. Matte is the opposite of gloss. Its coating is rougher, with light being dispersed from the image. This gives a more subdued and refined appearance to the printed sheet.Help, Advice and Tips for printing on Uncoated and Coated paperUse glossy paper for photograph printing. Glossy paper makes images "pop" off the page, though it tends to be less useful for large amounts of text, as the sheen is tiresome to read.When producing a printed product with long passages of text and fewer photos, choose a matte coated paper.It is possible to print document with matte paper then add a gloss finish to the images, but this requires special printing expertise. For a subdued, ecologically-friendly look and feel, premium uncoated stock is ideal.It is also important to know the paper thickness to ensure the right amount of ink is being used.For more information visit fredericklaw.co.uk
