Everything you need to know about offset printing

During our careers, we came across subjects that are occasionally questionable about its usefulness within the professional practice of our profession. This questioning can be explained by a cultural issue within the academy, that is, stigmatized by a large part of the student, predisposing us in an unreceptive way to the content that is taught in it.

Thus, another question may be for practical reasons, that is, due to the fact of not finding it within our practical framework at an academic level and in that sense, much less in the plane of professional practice.

What is offset printing?

To all these, it is necessary to take into account one thing, things work in a certain way for some reason and that is that everything happens for a reason, nothing is passive within our life and in that sense (and for this case), nothing is passive within the continuum of our academic training. For that reason, this article is written motivated to account for the so-called Pre-printing regarding its usefulness and importance, stating what its functions are in a brief and general way.

We will present some considerations about its guidelines and stages within the area of ​​graphic design.

First, we will consider color mode and is that in general, designers tend to work their models under a format of RGB type color, colors used to have a visualization through computer screens.

What is the problem with using this color format?

During the guidelines that respond to the making of mockups there might not be any problem. Nevertheless, the final product could be compromised With the use of the RGB format, although of course, this is coincidence and is that for practical purposes, the CMYK color format, which guarantees 100% a range of colors suitable for printing and in that sense, several aspects must be considered.

Can be used RGB format for all jobs relevant to the design of the mockup, but at the time of printing, it is It is advisable to adopt the model in the CMYK format.

The Bleedings are another essential aspect within the framework of the designs and that is that thanks to the bleedings, we elaborate our work on the basis of a margin of tolerance in terms of its edges, allowing us to face that possible margin of error present in the printing of our product. As regards action, it is necessary then exceed the cutting line at least 2mm away, to get a free impression of those white stripes that distort the edges of our mockup.

Margins are another point to consider when dealing with the demands of our clients, especially when the moment comes when it decides to adopt a text that will exceed the margins tolerance of our margins. The best thing to do in this situation is to introduce a margin of at least 7mm, thus increasing our tolerance margin to the topography that our client demands. It is about being aware of what frequently knocks on the door in a tedious way.

The resolution of our files should be an issue

This is the reduce or enlarge images. These can cost us quality, time and definition, therefore, it is advisable to use image editing programs, which include the reduction or enlargement function and images.

A good measure for him format of our images converting to PDF results. And it is that this format guarantees us a good relationship between our work and the final product, which, without a doubt, should be considered within the same plane.

La involuntary overprinting It is a headache in the development of new designs and our best solution is the use of programs that allow us to appreciate our models from a plane of options that exclude the overprint of our options, making sure to do it when it is really the case.
