Five tips for Avoiding Commercial Printing Problems
Pre-press production is the process of completing all work needed to successfully print a brochure, direct mail piece, an ad, book or other printed matter.
While the design process typically focuses on the overall look and feel, the pre-press process will involve image cropping, color correction, file conversion, making final corrections and proofing.
Pre-press files which are not prepared properly will create time delays to fix the problems or may result in problems with the actual printing process. It can not be stressed enough that “do it yourself” pre-press work is only for those with pre-press or printing experience in order to achieve desired results.
Tips For Pre-Press Success
Here are five tips for avoiding pre-press problems.
Create pre-press files with the right program. Always use pre-press software such as Adobe Photoshop, Illustrator and InDesign to create pre-press files. Using Microsoft PowerPoint or Microsoft Word to create a pre-press file for printing professional marketing materials such as brochures, catalogs or direct mail will lead to disaster.
Send the proper file type to your printer. Different printing companies will have different requirements for the type of file they want to use. Some printers will want a high resolution PDF file, others want the original Illustrator or InDesign file, and others may prefer something else entirely. It is always a good idea to talk to the printing company you will be using before starting the project to prevent having to redo any work.
Be aware of printing limitations. While many printing companies are similar in many respects, their actual equipment can vary dramatically. Some printers with smaller presses may not be able to print a given project as well as a printer with a larger press, if a project has a lot of solid color areas, for example. Other printers may be better equipped than others to handle complex folds or running a fifth or sixth color. Check your printer’s capabilities before you send over the pre-press files for pinting.
Outline all text. It is a good idea to outline all text within the pre-press file so there are no font issues. Font files may work fine for you while working on the project, but sometimes there can be problems with the fonts printing correctly when pre-press files are sent to the printer. By outlining all text in the pre-press file, you eliminate any need for font files and all text will print correctly.
Convert all RGB files to CMYK. A common problem printers have is that they receive a file that is set up for four-color process printing (CMYK), but the support files they receive such as photographs are in RGB format. This will create a delay in printing, additional costs to convert the file, or may lead to problems printing the project.

The growth of digital printing technology has brought technical advancements, more options, and exciting new features to today’s commercial printing. It has also meant that there is some confusion when choosing the right option for your next printed project. This article endeavours to shed some light on the advantages and disadvantages of digital printing and how those compare to traditional offset lithography. It also includes a handy check list to make the decision between offset print and digital print even easier!
Offset lithography is the most common high volume commercial printing technology. In offset printing, the desired print image is burned onto a plate and is then transferred (or offset) from the plate to a rubber blanket, and then to the printing surface. The lithographic process is based on the repulsion of oil and water. The image to be printed gets ink from ink rollers, while the non printing area attracts a film of water, keeping the non printing areas ink-free.
Mechanical Steps Eliminated in Digital Printing
Digital printing eliminates many of the mechanical steps required for conventional printing, including making plates and making the printing presses ready.
So … Which to choose? That all depends……
Advantages of Digital
• Shorter turnaround.
• Every print is the same. More accurate counts and less waste
• Cheaper low volume printing. While the unit cost of each piece may be higher than with offset printing, when setup costs are included digital printing provides lower per unit costs for very small print runs.
• Variable Data Printing is a form of customizable digital printing. Using information from a database or external file, text and graphics can be changed on each piece without stopping or slowing down the press or making new plates. For example, personalized letters can be printed with a different name and address on each letter. Variable data printing is used primarily for direct marketing, customer relationship development and advertising.
Advantages of Offset
• High image quality.
• Works on a wide range of printing stock including high gloss, heavy weight and textured stock.
• The unit cost goes down as the quantity goes up.
• Quality and cost-effectiveness in high volume jobs. While today’s digital presses are close to the cost/benefit ratio of offset for high quality work, they are not yet able to compete with the volume an offset press can produce.
• Many modern offset presses use computer-to-plate systems as opposed to the older computer-to-film work flows, further increasing quality.
Below is a check list to help you decide on the best option for you:
• Quantity. Offset printing has a front-end cost load. Short runs may have a high unit cost. But as quantities increase, the unit cost goes down with offset printing. Very short runs can be much more cost effective with digital printing; while larger quantities are likely to have a lower unit cost with offset printing.
• Printing medium. Do you need or want a special paper, finish or unusual printing surface, or unique size? The options are increasing continually for digital, but offset printing still offers the most flexibility.
• Colour. Digital presses use four-color process printing. If you need only black ink or one or two ink colours, offset printing may offer a more cost-effective solution. If you need four-color printing, digital may offer advantages in lower up-front costs.
• More on colour. If you’re planning to print using the Pantone® Matching System, offset printing will give you the best match, since it uses actual Pantone® ink. Digital printing simulates the colour using a four-color matching process, so some digital printers may offer less accurate colour matching on projects.
• Turnaround. If you need it fast, digital usually offers quicker delivery.
• Proofing. Digital offers accurate proofs since you see an actual sample of the printed piece. Accurate colour proofing for offset printing can be expensive.
• Customization. Without question, digital printing offers the most affordable way to customize marketing materials, direct mail pieces, letters, etc.
