Paper: The Suitability of the Stock for your Print Project

Posted by under ,
BJ Ball Swatch Books

Paper is to print, what canvas is to painting—you cannot have one without the other. As a designer, it is important to know that your choices around paper will impact the final output. The suitability of the stock when selecting paper for your print project includes a number of considerations. Let’s take a look: Types of Paper Paper, how it looks and feels, is going to have a big impact on the final printed result. And as such—should be an important design consideration early on in any project. Paper can be classified into six basic categories as follows: Uncoated Papers:...

Artwork: Photographic Images

photographic images

The use of photographic images in artwork creates a few important considerations that should always be checked. GSM investigates; Correct Colour Mode Photographic images should always be set to the correct Colour Mode—CMYK. RGB images used in CMYK-based printing can potentially create problems (including unexpected colour results). The best professional practice is to open any RGB images in an editing app (such as Adobe Photoshop) and change the Colour Mode—go to: Image > Mode > CMYK Colour. Image Resolution Image resolution, as measured in Pixels Per Inch (PPI), is critical to ensuring photos print correctly. If the resolution is too...

Artwork: Colour

CMY colour wheel

Colour is one of the areas that causes the most problems in print. Here are some things to be mindful of: Using The Correct Colour Model Regardless of the intended print process—artwork for print should always use the CMYK colour space—not RGB. This means: Artwork source files (e.g. Adobe Illustrator or InDesign) should be set up using the CMYK (Print) Colour Mode. All linked photographic images should also be converted from RGB to CMYK mode, resaved and relinked into your artwork. When you are adding colours into your artwork, make sure these are CMYK based colours. The only exception to this is...

Artwork – Document Set-up

Posted by under

Artworking (sometimes called mac’ing) is the process of taking a final design, and turning this into output ready artwork. Document set-up should be the final step before a file is dispatched to a printery. Being a competent artworker not only helps avoid potentially time consuming or costly mistakes. But also enables maximum benefit from print as you simply understand the medium better. Let’s look at some technical considerations to help you navigate this: Document Set-up Correct document set up is the first component for creating good artwork. For this topic, we will be using the below example project. This is...

Beyond Print – Binding

binding

Commercially printed multi-page documents can be bound in several ways. But by far, the most common are soft-cover Saddle-Stitching, squared spine Binding and hardback Case-binding. GSM takes a look... Saddle-Stitching (Soft-Cover) Saddle-stitching is the most common form of ‘soft-cover’ commercial binding. This process uses two or more staples inserted along the spine to hold the document together. Saddle-stitching is a machine process with little manual input, apart from the initial collating of the printed sheets, making this the most costeffective way to bind multi-page documents. As mentioned in our article "Folding" some digital print systems have saddle-stitching capabilities running off the...

Beyond Print – Folding

folding

Folding is usually one of the last steps in the print process and is most commonly done as a separate process after printing is complete (note; there are exceptions where folding is done straight off the end of the printing press). On a commercial level, folding is undertaken on a folding machine. These large industrial machines can crease, fold and counter-fold with high precision. Some folding machines also include binding capabilities—particularly saddle-stitching. Note also that some digital print systems include in-line capabilities that produce finished, bound documents directly off the end of the press. Sheet-fed offset lithographic printing presses do...

Beyond Print – Die-cutting

cardboard packaging prototype

Die-cutting (sometimes referred to as ‘knifing’) is a non-print-based process of stamping a form or shape out of a substrate (usually paper or board). These can be packaging forms such as  boxes. Or they can be design elements punched out of a flat surface. For example, a shape cut out of a brochure cover. Either way, the process is the same. The Process Die-cutting is undertaken after printing, using a special stamping press. A ‘die’ or knife block, mounted on the press, hits the printed sheets cutting the form. If the project is a constructed form, such as a box,...

Beyond Print – Foiling

digital foiling

The print embellishment of Foiling is a non-ink-based process. It adheres a micro-thin metal ‘foil’ onto a sheet of paper or board. Thus creating a very different aesthetic from metallic ink or toner—with a ‘true’ metal look. There are several methods of Foiling, GSM takes a look... Hot Stamp Foil Hot Stamp Foiling is similar to embossing/debossing but only uses a single (male) block—there is no female block. The block is heated and hits the foil material onto the substrate. This heat and impact pressure fuse the foil to the substrate surface. Note that the impact leaves a very slight deboss...

Beyond Print – Embossing & Debossing

embossing

Embossing and debossing print embellishments create a raised area on paper or board. These are the same process—the only difference is the result: Either raised (emboss) or recessed (deboss). GSM takes a look… Firstly, embossing/debossing is always done after printing is complete, as a separate process. The process uses a stamp-press or Letterpress loaded with two metal die-blocks—a male (raised) and a female (recessed) block. The blocks are loaded opposing each other on the stamp-press. As sheets of paper or card feed through the press—one block hits against the other, sandwiching the stock and creating a three-dimensional impression. Typically, the...

Beyond Print – Clear Coatings

Posted by under

There are many processes beyond printed colour which can be used to embellish or finish a printed piece. We often do these non-print processes separately after completeing the print. The most common embellishments are a print coating, foiling, embossing and die-cutting. GSM takes a look at print coatings… Clear Print Coating Print coatings are clear finishes with the primary purpose of protecting a printed piece from smudging, scuffing and general wear and tear. However, some coatings can also be part of the overall aesthetic. Here are the most common print coatings: Acrylic Varnishes Primarily used in Offset Lithography, Flexography and Rotogravure,...
