Sending flawed artwork to the press delays projects and drains marketing budgets. A solid pre-press checklist bridges the gap between screen design and physical production. Lebone Litho protects your deadlines by catching technical errors before they hit the press. In this article, learn about:

• Setting up files with the correct dimensions and bleeds.
• Managing image resolution for crisp, professional output.
• Converting fonts and colours to prevent substitution errors.
• Exporting print-ready PDFs for your digital printers.

We have all seen a compromised print job. The only thing worse than a blurry corporate logo, cut-off text, or washed-out colours is sending your campaign files to the press only to hear three days later that the fonts are missing and the images are too low-resolution to use, which drains your team’s time and pushes your launch date back.

Submitting print-ready artwork is the easiest way to keep your projects on schedule. As expert digital printers, Lebone Litho uses our in-house reproduction and DTP hub to verify every detail, but when your file is clean from the start, we can turn your job around even faster. 

The Baseline Requirements For Print-Ready Files

A beautiful design only works if the technical foundation is in place. Skipping these simple steps is one of the main reasons print jobs get delayed.

• Exporting as a high-resolution PDF/X-1a locks in your layout and prevents unexpected shifts. This specific format embeds all vital data, ensuring that text won’t reflow, images won’t jump out of alignment, and complex graphics won’t randomly drop out when opened on the printer’s software.
• Converting all artwork from RGB to CMYK stops colours from looking dull on physical paper.
• Keeping all images and raster graphics at 300 DPI at 100% size stops pixelation.
• Flattening transparency effects before saving stops the printer from misinterpreting drop shadows or glows.

Margins and Bleeds That Protect Your Layout

The guillotine cutting process always needs a little room for error. If you build your files exactly to the trim size, you risk damaging the final product.

• Adding a 3mm bleed on all sides protects your background colours from showing white borders after trimming.
• Placing essential contact details, legal fine print, and core branding at least 5mm inside the trim line establishes a protective internal buffer, guaranteeing your information won’t be accidentally sliced off during the final cutting phase.
• Including crop marks tells the bindery team exactly where the blade should cut the page.

Typography and Special Finishes Setup

Fonts and areas with heavy ink coverage need specific settings if you want them to print cleanly on a high‑speed press.

• Converting all text to outlines or curves prevents font substitution errors if the printer lacks your specific typeface.
• Using 100% K for body text keeps lettering sharp, while rich black formulas work best for large dark backgrounds.
• Placing special coatings, like UV or foil, on a separate, clearly named layer helps prevent costly misalignments and keeps those embellishments from interfering with the underlying CMYK ink layers. 

Relying on how a file looks on a monitor is a risky strategy because screens always display colours brighter than physical ink. Taking a few extra minutes to run through this checklist prevents costly reprints and makes you look like a seasoned professional.

Feel free to print this checklist out and pin it to your studio wall, or pass it along to your junior designers and marketing managers. It is the ultimate cheat sheet for avoiding file rejections and missed deadlines. 

Once your artwork is bulletproof, partner with expert digital printers who treat your files with the exact same respect you do.

FAQs and Answers

1. What does repro mean in printing?

Repro is short for reproduction and refers to the pre-press process used to prepare artwork for printing. It includes file verification, colour separation, image checks, font preparation, trapping and preparing the final printing form.

2. What files should I submit to a commercial printer?

Most commercial printers prefer a print-ready PDF, particularly a PDF/X-1a file. You should also provide any required linked images, original artwork files, brand guidelines and clear instructions for special finishes such as foil, varnish or spot UV.

3. How much bleed should be added to print artwork?

A bleed of 3 mm should normally be added to every side of the artwork. The bleed allows colours and images to extend beyond the final trim line, preventing unwanted white edges after the printed material is cut.

4. Should print artwork be supplied in RGB or CMYK?

Print artwork should usually be supplied in CMYK because commercial printing presses use cyan, magenta, yellow and black inks. RGB files are designed for screens and may produce unexpected or duller colours when converted for printing.

5. What resolution should images be for professional printing?

Images should generally be supplied at 300 DPI at their final printed size. Images with a lower resolution may appear pixelated or blurry, especially when they are enlarged within the artwork.

6. Should fonts be outlined before sending artwork to print?

Fonts should be converted to outlines or curves when possible. This prevents missing font and substitution errors if the printer does not have the original typeface installed. Keep an editable version of the artwork before outlining the text.

7. How would you measure the quality of a printout?

Print quality is commonly assessed through resolution, colour accuracy, sharpness, contrast and registration alignment. DPI can help measure image detail, while physical proofs and colour checks confirm whether the finished print matches the approved artwork.

8. Is 300 DPI or 600 DPI better quality?

A resolution of 300 DPI is suitable for most professional printing at the image’s original size. A 600 DPI image contains more detail and may be useful for fine linework, detailed scans or artwork that needs to be enlarged.
