A postcard that looks sharp on screen can still arrive with a logo trimmed too close to the edge, a brand color that prints dull, or a phone number that is hard to read. Those problems usually begin before the press starts. When you prepare artwork for commercial printing correctly, you protect your budget, your timeline, and the impression your business makes when the piece reaches a customer.
For a simple business card order, the setup may take only a few minutes. For a brochure, direct mail campaign, booklet, or large-format sign, a little more planning can prevent expensive changes later. Use this checklist before submitting your next print-ready file.
Start With the Finished Product, Not the Design File
Artwork requirements depend on what you are printing. A yard sign, a folded brochure, an EDDM postcard, and a window graphic may all begin as a digital design, but they do not use the same dimensions, materials, finishing options, or viewing distances.
Choose the final product size before you build the layout. If your postcard is 6 x 9 inches, set up the document at that finished size from the beginning. If it will fold, account for each panel and any fold adjustments. For booklets, confirm the finished page size, page count, binding method, and whether pages need to be supplied as single pages or printer spreads.
This step matters because resizing at the end can shift type, distort images, and create unwanted white borders. It also helps to decide early whether you need finishing such as coating, rounded corners, perforation, or hole drilling. These options can affect where important content should sit.
Set Up Bleed, Trim, and Safe Areas
Commercial printing involves more than the final size shown on a ruler. Paper moves through cutting equipment, and even precise trimming has a small degree of variation. Bleed and safe areas give your design room for that reality.
Bleed is the extra image or background that extends beyond the finished edge. A standard setup is typically 0.125 inch of bleed on every side. For example, a 4 x 6 inch postcard with bleed should be built at 4.25 x 6.25 inches. If a photo, color block, or pattern reaches the edge of the finished piece, it must extend into this bleed area.
The trim line is where the piece will be cut to its final size. Keep text, logos, QR codes, and other critical elements inside the safe area, generally at least 0.125 inch from the trim line. For signage, folded pieces, and products with grommets or hardware, allow more room when needed.
A common mistake is adding a thin border around the edge of a card or flyer. Because the piece may be trimmed slightly differently from one side to the next, that border can appear uneven. Full-bleed color or a wider interior border is usually the safer choice.
Use High-Resolution Images at Their Final Size
An image can look fine on a laptop and still print soft or pixelated. Screens display images using light, while print relies on tiny dots of ink. A file needs enough image data to hold detail at the size it will print.
For most commercial print pieces, use images that are 300 pixels per inch at their placed size. That last part is essential. A 300 PPI image may not remain 300 PPI if it is enlarged dramatically in the layout. A small web image stretched to fill an 8.5 x 11 inch flyer is likely to look blurry in print.
Avoid relying on screenshots, social media downloads, or images copied from a website for large printed pieces. They are often low resolution and may not have the rights required for commercial use. Start with the original photo whenever possible.
Large-format graphics are different because they are viewed from farther away. A banner may work well at a lower effective resolution than a postcard, depending on its final size and viewing distance. If you are ordering a large sign, share the intended dimensions and application before finalizing the file. That is faster than rebuilding a low-resolution design after submission.
Build Color for Print, Then Manage Expectations
Most commercial printing uses CMYK inks: cyan, magenta, yellow, and black. Most screens use RGB light. That difference means a bright color on a monitor may not look identical on paper, especially neon tones, electric blues, and highly saturated greens.
Set your document to CMYK when the software and project allow it. Convert placed RGB images if needed, and use CMYK brand values supplied for print rather than copying colors from a screen. If your brand has a specific Pantone color requirement, discuss it before ordering. Some jobs can use spot-color printing, while others are produced in standard full-color process printing. The best route depends on the product, quantity, budget, and how exact the color match needs to be.
Paper also changes color perception. A glossy postcard often makes images appear more vibrant, while an uncoated stock has a softer, more natural finish. A dark background can look rich on one paper and less intense on another. If color is critical for a major campaign, request a proof or talk through the stock and production method first.
Keep Type, Logos, and QR Codes Production-Ready
Small type and fine lines are where avoidable production issues tend to show up. Use readable font sizes for your audience and the product’s purpose. A disclaimer can be small, but a phone number or offer code should not require a magnifying glass.
Before exporting, make sure fonts are embedded in the PDF or converted to outlines when appropriate. Embedded fonts preserve the intended typeface if the receiving system does not have that font installed. Outlining can be useful for final logo artwork, but keep an editable version of your original file because outlined text is no longer easy to revise.
Use vector logos whenever possible. Vector files stay crisp at any size, making them the right choice for business cards, banners, event tents, and vehicle-scale graphics. Raster logo files can work only if they are high resolution at the final printed size.
QR codes deserve a real-world test. Keep them clear of folds and trim lines, maintain adequate contrast, and do not make them too small. Print one at actual size on an office printer and scan it with multiple phones. This simple check can save a direct mail campaign from sending customers to a code that will not scan.
Prepare Files for Mailing and Variable Data Carefully
Direct mail adds another layer of production planning. Your artwork must include a clear mailing area, room for the postage indicia or stamp, and any required addressing structure. An EDDM piece has its own format and postal requirements, which can differ from an addressed mail campaign.
If your campaign uses variable data – such as recipient names, unique offers, agent contact details, or location-specific messaging – separate the static design from the changing data fields. Verify the mailing list before production, not after. Check column names, postal addresses, ZIP Codes, merge fields, and any personalization rules.
For a local promotion, it can be tempting to use every inch of the mailer for marketing. But a clean mailing panel is part of getting the piece delivered properly. Build that space into the design from the start.
Export a Print-Ready PDF and Review It at Full Size
A high-quality PDF is the standard final format for many commercial print jobs. Export with crop marks only if requested, include bleed, embed fonts, and preserve image quality. Avoid sending a flattened screenshot, a presentation file, or a compressed PDF intended for email unless your print partner specifically asks for it.
Then review the exported PDF, not just the original design file. Zoom in to inspect small text, image edges, and logos. View it at 100% to judge scale. Check every page of a multipage document, including the back cover and inside panels. Confirm that dates, prices, URLs, phone numbers, and call-to-action language are current.
A practical preflight review should catch these four common issues:
- Missing bleed on designs that print to the edge
- Low-resolution images enlarged beyond their usable size
- Critical text or QR codes placed too close to trim or folds
- Incorrect colors, outdated contact information, or missing pages
Ask Questions Before the Deadline Becomes the Problem
The best time to ask about file setup is before your campaign is due, not after the artwork has gone to press. If you are unsure about dimensions, stock, folds, mailing layout, or file export settings, send the question early along with a description of the finished product you need.
Pink Hippo works with businesses that need everything from routine collateral to time-sensitive signs and direct mail campaigns, so the production team can help identify issues before they become reprints or delays. That support is especially useful when a job combines printing, addressing, and mailing.
Your artwork does not need to be complicated to work hard for your business. It needs to be clear, correctly built, and checked with the finished piece in mind. Give the file a final production-focused review, and your next postcard, brochure, sign, or mailer will be ready to make a polished first impression.
