You’ve designed the perfect business card, brochure, or poster. The colors look great on your screen. You’re ready to send it to the printer. But before you hit “send,” there’s one critical step that can make the difference between a flawless print job and a costly reprint: preparing your files correctly.
At Linprint, we review hundreds of design files every week. Some are print-ready and go straight to production. Others need adjustments before we can print them. Here’s what we look for — and what you need to know to prepare your files the right way the first time.
File Format: PDF is King
The single best format for print is PDF/X-1a. This is a special type of PDF designed specifically for professional printing. It embeds fonts, flattens transparency, and ensures color accuracy.
Most design programs (Adobe Illustrator, InDesign, Photoshop, Canva Pro, Affinity Designer) can export to PDF/X-1a. When you save your file, look for export settings and choose PDF/X-1a if it’s available.
If PDF/X-1a isn’t an option, a standard high-quality PDF will work, but make sure fonts are embedded and images are at least 300 DPI (more on that below).
We also accept:
- Adobe Illustrator (.ai)
- Adobe InDesign (.indd) — package the file with fonts and linked images
- EPS with outlined fonts
- High-resolution TIFF or PSD (for images)
We do NOT recommend:
- Microsoft Word, PowerPoint, or Publisher files (these aren’t designed for professional printing)
- Low-resolution JPGs from the web
- PNG files with transparency (unless it’s for a specific application like stickers)
If you only have a Word or PowerPoint file, we can often work with it — but expect that we’ll need to rebuild certain elements to meet print quality standards. It’s better to design in a program built for print from the start.
Resolution: 300 DPI Minimum
DPI stands for “dots per inch,” and it determines how sharp your printed image will be. For professional printing, 300 DPI is the minimum.
Images that look crisp on your computer screen (which typically displays at 72-96 DPI) will look blurry or pixelated when printed at actual size if they’re below 300 DPI.
How to check your image resolution:
- In Photoshop: Image → Image Size (look for “Resolution”)
- On Mac: Right-click image → Get Info → More Info (look for “Resolution”)
- On Windows: Right-click image → Properties → Details (look for “Horizontal/Vertical Resolution”)
If your image is below 300 DPI, you have two options:
- Find a higher-resolution version of the image. You can’t increase resolution after the fact — it just enlarges the existing pixels and makes things blurrier.
- Use the image at a smaller size. A 150 DPI image printed at half its original size becomes 300 DPI.
Common mistake: pulling images from your website or social media. These are almost always 72 DPI and will not print well. Always use the original high-resolution file.
Color Mode: CMYK for Print
Computer screens display color using RGB (Red, Green, Blue). Printers use CMYK (Cyan, Magenta, Yellow, Black).
If you design in RGB and send it to print, the colors will shift — often dramatically. Bright blues become duller, vibrant greens shift toward cyan, and reds can look muddy.
Before exporting your file, convert to CMYK.
- In Photoshop: Image → Mode → CMYK Color
- In Illustrator: File → Document Color Mode → CMYK Color
- In InDesign: Set your color swatches to CMYK when you create the document
If you’re using brand colors, make sure you have the CMYK values, not just the RGB or HEX codes. Your brand guidelines should include both.
What about Pantone (PMS) colors? If you need an exact color match — for example, your logo uses a specific Pantone color — let us know. We can print with Pantone spot colors on certain products for perfect color accuracy. Just make sure the Pantone color is specified in your file.
Bleed: Add It or Risk White Edges
Bleed is the extra area around the edge of your design that extends beyond the final trim size. When we print and cut your piece, slight variations in cutting (even with precision equipment) mean we need that extra margin to ensure your design goes all the way to the edge with no white borders.
Standard bleed is 0.125 inches (1/8″) on all sides.
For example, if you’re printing a 3.5″ x 2″ business card, your design file should be 3.75″ x 2.25″ (adding 0.125″ on each side).
Your important content — text, logos, phone numbers — should stay at least 0.125″ inside the trim line. This is called the “safe area.” Anything outside this area risks getting cut off.
How to set up bleed:
- In Illustrator/InDesign: When you create a new document, there’s a “Bleed” field. Set it to 0.125″.
- In Photoshop: Manually create a document that’s 0.25″ larger than your final size (0.125″ on each side).
- In Canva: Use the “Add Bleed” option when exporting (Canva Pro feature).
If your design has a white or light-colored background, bleed is less critical (a slight white edge won’t be noticeable). But if your background is a dark color or a photo that extends to the edge, bleed is absolutely essential.
Fonts: Outline or Embed
When you use fonts in your design, the printer needs access to those exact fonts to display your text correctly. If we don’t have the font installed, your text will substitute with a default font — and your design will look wrong.
Here’s how to avoid this:
Option 1: Outline your fonts (recommended for logos and simple layouts)
Outlining converts your text from editable letters into vector shapes. This means the font file is no longer needed. In Illustrator, select your text and go to Type → Create Outlines.
Pros: Guarantees your text will look exactly as designed.
Cons: You can’t edit the text after outlining. Save a copy of your file with live text before outlining.
Option 2: Embed your fonts (for PDFs)
When you export to PDF, choose settings that embed fonts. Most programs do this automatically in PDF/X-1a. You can verify by opening the PDF in Adobe Acrobat and going to File → Properties → Fonts. All fonts should say “Embedded Subset.”
Pros: Text remains editable in the original file.
Cons: Requires correct export settings.
If you’re sending us an Illustrator or InDesign file, either outline your fonts or include the font files in your package.
File Naming: Make It Clear
This seems minor, but it saves time and prevents errors. Name your file something descriptive:
Good: LinprintBusinessCard_Front_Final.pdf
Bad: Untitled-3-final-FINAL-v2.pdf
If you have multiple files (front and back of a business card, multiple page layouts), label them clearly: Front, Back, Page1, Page2, etc.
Proofing: Catch Errors Before We Print
Before you send us your file, do a final check:
- Spelling and grammar: We’ll print exactly what you send. Typos are expensive to fix after printing.
- Contact information: Double-check phone numbers, email addresses, and website URLs.
- Alignment: Make sure text and design elements are aligned properly.
- Image quality: Zoom in to 100% and check that images are sharp, not pixelated.
At Linprint, we review every file before printing and provide a digital proof for your approval. Nothing goes to press without your written sign-off. But catching errors early saves time and gets your job done faster.
What If You’re Not Sure?
If you’re not confident your file is print-ready, send it to us anyway. We’ll review it and let you know if anything needs adjustment. We can often fix minor issues (low resolution on a small element, missing bleed, etc.) for a small file prep fee.
For more complex projects — or if you’re starting from scratch — our in-house design team can handle the entire project from concept to print-ready file.
