Letters

Letter paper is used to personalize the documents of your company or institution with its information as a kind of introduction.
In this way, multiple documents can be delivered using the letter paper (quotes, invoices, contracts, etc.).

Sometimes the letter paper is designed in two different ways. A first (1st) sheet of letter paper, more detailed, with the logo and information more visible. And a second (2nd) sheet of letter paper, slightly more simplified, with a smaller logo, but more legible. The latter is used on the inside sheets of the documents to simplify the design and make the contents easier to read.

Although the sheets of letter paper can have multiple formats, the most common format is A4, as the sheets can later be reprinted in the user's printers and can also be inserted in standard envelopes.

Letter paper is usually printed on one side in one of the following ways:

• colour (four-colour)
• in black
• in two colours
• in Pantone colours
• a combination of all of them

Sometimes companies and institutions have a corporate image manual in which they indicate the exact colours (usually Pantones) to be used during the printing of their stationery, in this case: Letters.

The most commonly used medium for printing letter paper is offset or recycled paper or similar specialities, since, by definition, it is necessary to use porous paper that allows reprinting in office printers or writing by hand on them.

The weights to be used in letter paper are usually between 80 and 120 grams.
