Before diving into the how, here is why PDF is what we ask for.
A properly exported PDF locks in your fonts, colors, images, and layout exactly as you designed it — regardless of what software or operating system we open it on.
PDF is the only common format that can carry bleed information and printer's marks (trim marks, crop marks) as part of the file itself — which is essential for accurate cutting.
Transparency effects like drop shadows, glows, and overlapping elements can cause problems in other formats. A correctly exported PDF flattens or preserves transparency in a way that prints predictably.
Before you export, make sure your file meets all of these. We'll go through each one in detail below.
Common mistakes to avoid
Illustrator is the gold standard for print-ready PDFs, especially for vector artwork, logos, and anything that needs to scale without quality loss.
Confirm your document color mode is CMYK
Go to File → Document Color Mode → CMYK Color. If it says RGB, switch it before exporting. Any RGB colors will shift when converted to CMYK at the printer.
Confirm bleed is set on your artboard
Go to File → Document Setup and check your bleed values. You should see a red bleed border around your artboard. Make sure your background color or image extends into this red area on all sides.
Outline all fonts
Select all (Ctrl/Cmd + A), then go to Type → Create Outlines. This converts all text to vector shapes so your fonts are embedded in the file without relying on the printer having the same fonts installed.
Export as PDF using the correct preset
Go to File → Save a Copy (or Save As) and choose Adobe PDF. In the PDF dialog, select the PDF/X-1a:2001 or PDF/X-4:2008 preset from the dropdown. PDF/X-4 is preferred if your file uses live transparency effects — it handles them better than X-1a.
Enable bleed and marks in the export dialog
In the PDF export dialog, click Marks and Bleeds on the left sidebar. Check "Trim Marks" and "Use Document Bleed Settings." This includes crop marks in the file so we know exactly where to cut, and carries your bleed into the exported PDF.
Set image compression to maximum quality
Under the Compression tab in the PDF dialog, set image quality to Maximum or do not downsample images. Aggressive compression reduces image quality at print size even if it looks fine on screen.
InDesign is built for multi-page print documents — brochures, booklets, notepads, and anything with multiple pages or complex layouts.
Confirm bleed is set in your document
Go to File → Document Setup and check your bleed values under the Bleed and Slug section. You should see a red bleed border on your pages. Extend all backgrounds and images into this area.
Check for missing links and fonts
Go to Window → Links to confirm all placed images show no warning icons. Go to Type → Find Font to confirm no missing fonts are listed. Resolve any issues before exporting — missing links will print as low-resolution previews.
Export as PDF/X-4
Go to File → Export and choose Adobe PDF (Print). In the export dialog, select PDF/X-4:2008 from the Standard dropdown. This preset handles transparency correctly and embeds all fonts automatically.
Enable marks and bleed
Click Marks and Bleeds in the left sidebar of the export dialog. Check "Crop Marks" and "Use Document Bleed Settings." This tells InDesign to include trim marks and carry your bleed settings into the exported file.
Set color output to CMYK
Under the Output tab, set Color Conversion to "Convert to Destination" and set the Destination to a CMYK profile such as U.S. Web Coated (SWOP) v2. This ensures any RGB images in your document are converted to CMYK on export.
Photoshop is best for photo-based designs. It has limitations for print production compared to Illustrator and InDesign, but it can still produce a solid print-ready PDF when set up correctly.
Set your document to CMYK before you start
Go to Image → Mode → CMYK Color. Do this early in your process — converting to CMYK after heavy editing can shift colors. Check your colors after converting and adjust if anything looks off.
Set your canvas size to include bleed
Photoshop has no native bleed setting. Add your bleed manually by making your canvas larger than your trim size. For a 4×6 inch print with 0.125 inch bleed, your canvas should be 4.25×6.25 inches. Use guides to mark where the trim line falls so you know where important content should stop.
Flatten your image before exporting
Go to Layer → Flatten Image. This merges all layers and resolves any transparency or blending mode effects into a single flat image. Photoshop PDFs with live layers and transparency can sometimes produce unexpected results at the printer.
Save as Photoshop PDF
Go to File → Save As and choose Photoshop PDF. In the Save PDF dialog, select PDF/X-1a from the preset dropdown. Under Compression, set Image Quality to Maximum. Under Output, confirm the color profile is set to your CMYK working space.
A note on trim marks in Photoshop
Photoshop does not add trim marks automatically the way Illustrator and InDesign do. If trim marks are required, the cleanest solution is to place your flattened Photoshop file into Illustrator or InDesign and export from there with marks enabled. Alternatively, let us know when you submit your file and we can add them on our end.
Canva is a great tool for quick designs and works well for many of our print products. Follow these steps to get the best possible file out of it.
Enable print bleed in your design
Go to File → Print bleed and toggle it on. Canva will display a bleed border around your design and a safe area guide inside it. Make sure your background extends to the outer bleed border and all important content stays inside the inner safe area guide.
Download as PDF Print
Click Share → Download and select PDF Print from the file type dropdown. Do not use PDF Standard — it is optimized for screens, not print, and uses lower resolution and RGB color.
Check "Crop marks and bleed"
Before downloading, check the box for "Crop marks and bleed." This includes your bleed area and adds trim marks to the exported PDF so we know exactly where your design ends and where to cut.
Flatten PDF if possible
Canva exports are generally print-safe, but if you are using transparency effects or overlapping elements, open your exported PDF in Adobe Acrobat and use Print Production → Flattener Preview to flatten transparency before sending it to us.
Canva limitations to be aware of
Canva works in RGB by default and does not export true CMYK PDFs. Colors may shift slightly in print compared to what you see on screen. For designs where exact color matching is critical — such as brand materials with specific Pantone colors — we recommend using Illustrator or InDesign instead. For most everyday print products the color shift is minimal.
Always proof your PDF before sending it
Open your exported PDF in Adobe Acrobat Reader and zoom in to check that fonts, images, bleed, and trim marks all look correct. What you see in Acrobat is very close to what will print.
Use Acrobat's Output Preview to check colors
In Adobe Acrobat Pro, go to Tools → Print Production → Output Preview. This shows you exactly how your colors will separate and flags any RGB objects that didn't convert to CMYK.
Rich black for large dark areas
For large solid black backgrounds, use rich black (C:60 M:40 Y:40 K:100) instead of pure black (K:100 only). Pure black can look washed out at large sizes. For small text, stick to K:100 only to keep it sharp.
Not sure if your file is right?
Bring it in or email it to us before placing your order. We check every file before it goes to press and will let you know if something needs to be fixed. We can also handle file setup and PDF export for a small fee if you'd rather leave it to us.
