Whether you are printing custom yard signs, designing a vehicle wrap, or ordering vinyl banners, having your artwork prepared correctly is the single most important step to achieving a high quality finished product. While professional sign shops like Blue Hen Signs and Design offer full service graphic design, submitting your own premade files requires a basic understanding of what makes an image production ready.
Improperly formatted files can lead to blurry prints, distorted text, or unexpected design fees due to the extensive cleanup time required. This guide outlines the essential file guidelines you need to follow to guarantee flawless print results.
The Golden Rule: Only Include What You Want Printed
When submitting your artwork, cleanliness is key. Your file should strictly contain the final graphic element you want produced.
- Do not include extra white space around the image.
- Do not embed written artwork instructions directly into the design space.
- Pro Tip: If you need to include layout preferences or special design notes, save them in an entirely separate text file to keep your production graphic clean.
Vector vs. Raster: Why Math Matters in Printing
Understanding the difference between vector and raster formats is crucial for large format printing like banners and signage.
- Vector Format (The Gold Standard): Built from precise mathematical points rather than pixels, vector graphics can be scaled up to the size of a billboard without losing an ounce of quality. Your lines will stay perfectly crisp and sharp.
- Raster Format (The Pixel Trap): Formatted from small square dots called pixels, raster images become blurry, pixelated, and display jagged edges when you blow them up to larger sizes.
Preferred File Formats for Seamless Printing
To ensure your design transitions perfectly from your computer screen to the physical sign, prioritize these industry-standard formats:
- Adobe Illustrator (.AI) & Encapsulated Postscript (.EPS): These are original, editable working vector files. When submitting these, always convert your text to outlines and ensure no low-resolution raster images are embedded inside.
- Portable Document Format (.PDF): A universally popular choice because it displays accurately on any machine. Ensure your PDF is Vector Only by preserving Illustrator or EPS editing capabilities when you save it.
Formats to Avoid (And Why They Cost You Extra)
Certain file formats are considered unacceptable for immediate printing because they require extensive reconstruction by a graphic designer. Submitting these usually results in added design time fees:
- Corel Draw (.CDR): Most modern print shops do not utilize Corel Draw. If this is your native program, export your work as an .EPS or .PDF before sending.
- Standard Web Images (.JPG, .PNG, .GIF): These are raster formats. Unless they are natively shot at a very high resolution, they will distort when printed on large signage.
- Office Documents (.Doc, .XLS, .PPT): Microsoft Word, Excel, and PowerPoint are completely unusable for printing graphics. They are, however, great tools to use for writing down your project instructions.
The Photoshop Exception
While vector is always preferred, high resolution Adobe Photoshop (.PSD) and .TIFF files are acceptable in specific scenarios. If your design features complex digital paintings, intricate textures, or detailed photography, a high-quality raster format is necessary. If you are utilizing a Photoshop file, it is highly recommended to speak directly with your printer to confirm the resolution requirements before submitting.
