To help your posters print accurately and look their best, please prepare your artwork using these guidelines:
Choose the poster material that best matches the appearance, display location, and durability your project requires.
Our 8 mil photo paper is an excellent choice when image quality and vibrant color are the priorities. Its smooth printable surface reproduces photographs, detailed graphics, gradients, and rich colors with a crisp, professional appearance.
Our 9 mil semi-gloss paper provides a slightly heavier feel with a smooth, professional finish. The subtle sheen enhances color and detail while helping reduce the strong reflections associated with high-gloss surfaces. It is a versatile choice for posters containing both photographs and text.
Choose 8 mil photo paper when photographs, artwork, and vibrant image reproduction are most important. Choose 9 mil semi-gloss paper when you want a slightly heavier poster with a balanced finish that works well for both images and easy-to-read text.
Both materials are intended primarily for indoor use. Posters displayed outdoors or in areas exposed to moisture should be properly protected or placed inside a weather-resistant display.
“Mil” refers to material thickness. One mil equals one-thousandth of an inch.
Our custom posters are digitally printed in full color using the CMYK printing process. Cyan, magenta, yellow, and black inks are combined to reproduce photographs, illustrations, logos, gradients, and a wide range of colors.
Our high-resolution printing process produces rich colors, smooth tonal transitions, crisp lettering, and detailed images on both 8 mil photo paper and 9 mil semi-gloss poster paper.
Full-color printing allows you to include photographs and multiple colors without being limited to one or two ink colors.

For the most accurate results, artwork should be created and saved in CMYK color mode. Files submitted in RGB will be converted to CMYK before printing, which may cause certain bright colors to appear slightly different.
Computer monitors and mobile devices produce colors using illuminated RGB light. Printed posters reproduce colors with CMYK inks, so the finished poster may not exactly match what appears on your screen.
White Areas
Our posters are printed on white material. Areas that appear white in your design normally receive no ink, allowing the white paper to show through.
Matching Brand Colors
If your business uses specific brand colors, include the appropriate CMYK or Pantone color information with your artwork. We will make every reasonable effort to reproduce your colors accurately, but exact Pantone matches cannot be guaranteed with CMYK digital printing.
Large Black Areas
For deeper, richer black backgrounds, use a rich-black build of C60 M40 Y40 K100 rather than 100% black alone. Small black text and thin black lines should generally use 100% black only for the sharpest reproduction.

Lamination adds a clear protective film to the printed surface of your poster. It improves
durability and helps protect the print from fingerprints, light scratches, dirt, and occasional
moisture.
Matte lamination provides a smooth, low-glare finish with a soft, professional appearance. It makes text and graphics easier to view under bright lights or near windows where reflections may be a concern.
Matte lamination can slightly soften colors and contrast, producing a more subtle and refined appearance.
Recommended for:

Gloss lamination provides a shiny, reflective finish that makes colors appear brighter and photographs look more vibrant. It increases contrast and gives the poster a bold, polished appearance.
Because the surface reflects light, gloss-laminated posters may show more glare and fingerprints than posters with matte lamination.
Recommended for:
Choose matte lamination when reduced glare, readability, and a softer professional appearance are most important. Choose gloss lamination when you want stronger color, increased contrast, and a bright, eye-catching finish.
Lamination improves durability and moisture resistance, but it does not make a paper poster completely waterproof or suitable for permanent outdoor display.
Custom posters can be printed in many different sizes. Popular sizes include 11″ × 17″, 12″ × 18″, 18″ × 24″, 24″ × 36″, and 27″ × 40″. Custom sizes may also be available. Contact us with the dimensions of your display area if you need help selecting the right size.
We offer 8 mil photo paper and 9 mil semi-gloss poster paper. Both materials produce vibrant color and sharp detail but provide slightly different appearances and thicknesses.
The 8 mil photo paper is an excellent choice for photographs, artwork, and designs where vivid image reproduction is the priority. The 9 mil semi-gloss material has a slightly heavier feel and a balanced finish that works well for posters containing both images and text.
Yes. Matte and gloss lamination are available for added protection and durability. Matte lamination reduces glare and provides a softer appearance, while gloss lamination makes colors look brighter and increases contrast.
Our photo and semi-gloss poster papers are intended primarily for indoor use. Lamination adds moisture resistance but does not make a paper poster completely waterproof. Outdoor posters should be placed inside a weather-resistant sign holder or protective display.
Yes. We can turn high-resolution photographs into custom posters and enlargements. The photograph must have sufficient resolution for the requested poster size. We can review your image and let you know whether it is suitable for printing.
Yes. Highridge Graphics offers professional graphic design services. Send us your logo, wording, photographs, preferred colors, and desired poster size, and we can create a professional poster design for you. A proof will be provided for your approval before printing.
Artwork and photographs should be at least 300 DPI at the final printed size for the sharpest results. Images downloaded from websites or social media are often too small for quality poster printing.
A print-ready PDF/X-4 file is recommended. We can also accept high-resolution JPEG, TIFF, EPS, and Adobe Illustrator files. Fonts should be converted to outlines or embedded, and all linked images should be included.
Yes. Add 0.125″ bleed on all four sides when colors or images extend to the finished edge. Keep important text, logos, and design elements at least 0.25″ inside the trim edge.
Printed colors may look slightly different from colors displayed on a monitor or mobile device. Screens use RGB light, while posters are printed using CMYK inks. For the most predictable results, create and submit your artwork in CMYK color mode.
Include the appropriate CMYK or Pantone color information with your artwork. We will make every reasonable effort to reproduce your brand colors accurately, but exact Pantone matches cannot be guaranteed with CMYK digital printing.
Yes. Posters can be displayed in standard or custom frames. Let us know the exact opening size of your frame so the poster can be produced at the correct dimensions.
Poster pricing depends on the finished size, material, quantity, lamination choice, and whether graphic design services are required. Request a free quote with your specifications for accurate pricing.
Production time depends on the poster size, quantity, finishing options, artwork readiness, and current workload. If you need your posters for a specific event or deadline, include that date with your quote request.
A digital proof is provided when Highridge Graphics creates or adjusts your artwork. Carefully review all wording, spelling, contact information, dimensions, and layout before approving the proof.
Handle posters with clean, dry hands and avoid bending or folding them. When not displayed, roll the poster carefully with the printed side facing outward and store it in a protective tube. Keep unlaminated posters away from moisture and direct sunlight.
