Print File Mistakes Toronto Businesses Make (and How to Fix Them)

Print file preparation and commercial printing materials

I've seen this happen more times than I can count in my 15+ years in the trade.

You spend hours getting the design right. The colours look good on screen, the wording is approved, and everyone is ready to order.

Then the proof arrives, and something is off.

Maybe a thin white line appears along the edge. Maybe the colours look duller than expected. Maybe the logo is blurry, a font has changed, or an important detail has been cut off.

Tell me if this sounds familiar…

In my experience, these problems are usually not caused by the printing press. They start with small file-preparation mistakes that are easy to miss before artwork reaches production. I've watched good jobs go sideways over details that seemed minor on screen but became expensive once they hit print.

Whether you're ordering business cards in Toronto, preparing a brochure campaign, or developing custom packaging in Toronto, a proper file review can save you time, money and an expensive reprint.

I'm Ryan, a print broker, and these are seven of the most common print file mistakes I've seen over the years — and how to fix them before you order.

1. You're Missing Bleed

A design that reaches the edge needs extra artwork beyond the trim line.

Bleed is the area that extends past the final cut size. It gives the printer room to trim the piece without leaving unwanted white edges.

In my years handling print jobs, missing bleed has been one of the most common causes of avoidable reprints — especially on pieces that look simple at first glance.

For most standard commercial printing, 0.125 inches, or 3 mm, of bleed on every side is common. Larger products, such as signs or banners, may require different specifications.

For example, if your finished business card is 3.5 × 2 inches, your artwork may need to extend to 3.75 × 2.25 inches when bleed is included.

How to fix it

  • Set your document to the correct final trim size.
  • Add the required bleed on all four sides.
  • Extend backgrounds, photos and colour blocks completely into the bleed area.
  • Keep text, logos and important information inside a safe margin.
  • Check the printer's specifications before exporting the final file.

The same principle applies to brochure printing in Toronto, flyers, postcards, labels and packaging. Anything designed to print to the edge needs enough extra artwork for a clean trim. It's one of the first things I check now because I've seen how quickly a small setup oversight can spoil an otherwise strong piece.

2. Your File Is in RGB Instead of CMYK

Your screen uses light. Your printed piece uses ink or toner.

Screens display colour using RGB: red, green and blue. Commercial printing generally uses CMYK: cyan, magenta, yellow and black.

RGB can produce bright, vivid colours that do not translate exactly to print. When a file is converted at the last minute, bright blues, greens and oranges may shift noticeably. Over the years, I've had clients show me screen colours they loved, only to be surprised when the printed version felt flatter because the file was never prepared properly for press.

That does not mean your printed colours will look bad. It means you should manage the conversion before production rather than leaving it to chance.

How to fix it

  • Create your document in CMYK when possible.
  • Convert placed images to CMYK before exporting.
  • Review important brand colours after conversion.
  • Request a proof when exact colour matching is especially important.
  • Share your brand standards or colour references with your print provider.

This matters for everything from business cards to retail packaging. If your Toronto business relies on consistent branding across brochures, signage and custom packaging, colour management should be part of the file review. After 15+ years in print, I can tell you that colour issues are much easier to prevent before production than explain after delivery.

Quick reminder: Print colours can also vary depending on paper stock, coating, ink coverage and the production method. A digital screen is not a perfect preview of the final printed piece.

3. Your Images Are Too Low-Resolution

An image can look perfectly fine on your monitor and still print blurry.

Most commercial print projects use images that are approximately 300 PPI at their final size. A small image downloaded from a website may look sharp on a phone or laptop but become pixelated when enlarged on a brochure, poster or package. I still see this regularly: a file looks fine in a quick email preview, but once it is scaled for print, the softness becomes obvious.

The issue is not simply the number shown in an image file's properties. What matters is the effective resolution at the size it will be printed.

For example, a 1200-pixel-wide image may work well at four inches wide, but it will not necessarily look sharp when stretched across a large banner.

How to fix it

  • Use original, high-resolution photos whenever possible.
  • Check placed images at 100% zoom.
  • Avoid enlarging small web images.
  • Replace blurry logos with vector versions.
  • Use vector artwork for logos, icons and simple illustrations whenever possible.
  • Confirm that product photos are large enough for the finished size.

If you're preparing artwork for brochure printing in Toronto, review every photo before submitting the file. A blurry image can make an otherwise professional marketing piece look unfinished. I've had to flag this on plenty of jobs before they went to press, and catching it early has saved clients from paying for pieces that never would have made the right impression.

4. Your Fonts Are Missing or Not Properly Embedded

A font problem can change your entire layout.

If the required fonts are not embedded in your PDF or converted to outlines, text may reflow or be replaced when the file is opened on another computer.

That can change line breaks, headlines, spacing and alignment. It may also create problems with special characters or fonts used in logos. In my experience, font issues are one of those technical problems that seem small until they quietly change the entire look of a finished piece.

How to fix it

  • Export a print-ready PDF with fonts embedded.
  • Convert display type, logos and other fixed elements to outlines when appropriate.
  • Do not assume that sending font files separately will solve the problem.
  • Review the exported PDF carefully before sending it.
  • Keep an editable version of the file before outlining text.

Outlining text removes editability, so it is not always the right choice for every project. The best approach depends on the file, the production method and whether future changes are expected.

At Morningstar Printing, I review PDFs and identify font issues before the job moves into production. That extra check can prevent a simple design file from becoming a costly correction — the kind of mistake I've learned to spot after years of seeing where files tend to break.

5. You've Left Out Crop Marks, or Left the Wrong Guides Visible

Crop marks indicate where the finished piece should be trimmed. Safe margins show where important content should stay away from the edge.

Common problems include:

  • Missing crop marks
  • Crop marks placed incorrectly
  • Guide lines accidentally exported
  • Text or barcodes positioned too close to the trim
  • Important design elements sitting inside the bleed area

Crop marks are not a substitute for bleed. You generally need both: bleed for edge-to-edge artwork and trim information to help communicate the finished size.

How to fix it

  • Use separate guides for bleed, trim and safe margins.
  • Keep critical content away from the trim line.
  • Hide non-printing guides before exporting.
  • Export using the printer's requested PDF settings.
  • Confirm whether crop marks should be included for your specific project.

Different printers and production workflows may have different preferences. If you are unsure, ask before submitting the file rather than guessing. As a broker, I've learned that a quick check upfront is always easier than trying to fix a trimming problem after a job has already moved forward.

6. You're Sending the Wrong File Format

A file that works for the web may not be suitable for the press.

PNG, JPG, GIF, Word and PowerPoint files can be useful for digital content or early concepts. They are not always reliable master files for commercial printing.

A low-resolution JPG may contain compression artifacts. A Word document may reflow when opened on another computer. A PowerPoint file may use RGB colours, missing fonts or images that are not large enough for print.

For most commercial projects, a properly exported PDF is the safest starting point. I recommend this constantly because I've seen too many jobs slowed down, rebuilt or corrected simply because the source file was never meant for professional production.

How to fix it

  • Send a press-ready PDF when requested.
  • Use the printer's preferred PDF standard, such as PDF/X-1a, when appropriate.
  • Embed fonts or outline key text.
  • Include the correct bleed and trim information.
  • Use high-resolution images and vector logos.
  • Keep your original InDesign, Illustrator or other editable file for future revisions.

For custom packaging in Toronto, you may also need a dieline, separate artwork layers or specific technical settings. Packaging files should be reviewed carefully because folds, cuts and glue areas all affect the final result. In my experience, packaging is where small file mistakes get expensive fast, because one missed technical detail can affect the whole piece.

7. You're Using AI-Generated Artwork Without Checking It

AI-generated artwork can be useful for concepts, backgrounds and creative campaigns. But it still needs a professional preflight before it goes to print.

AI artwork may include:

  • Low native resolution
  • Strange details or distorted shapes
  • Unwanted text or symbols
  • Banding, noise or visible artefacts
  • RGB colour profiles
  • Unclear commercial usage rights

These issues can become much more obvious when the image is printed at a large size or used on packaging.

How to fix it

  • Check the artwork at 100% before placing it in your layout.
  • Make sure it has enough resolution for the final printed size.
  • Remove unwanted text and visual artefacts.
  • Convert the file to the required colour profile.
  • Add bleed if the image reaches the edge.
  • Confirm that your AI platform permits commercial use.
  • Treat the image like any other photograph or raster graphic.

AI can speed up the creative process, but it does not replace production review. A beautiful screen image still needs to be technically ready for paper, board, fabric or signage. I've seen promising artwork fall apart at the production stage because nobody stopped to check how it would actually reproduce in print.

Your Preflight Checklist Before You Order

Before sending your artwork, confirm that:

  • The document is the correct final size.
  • Bleed has been added on every required edge.
  • Text and logos are inside the safe margin.
  • Images are high-resolution at their final size.
  • Colours are prepared for the intended print process.
  • Fonts are embedded or outlined.
  • Crop marks and trim information are correct.
  • Non-printing guides are hidden.
  • The file is exported in the requested format.
  • AI-generated artwork has been checked for quality and usage rights.
