- Printer Restraints
Print width depends on the type of paper.
Matte Photo Paper: Maximum width 36 inch
Glossy Photo Paper: Maximum width 42 inch
We cannot always guarantee a perfect print: factors such as the image’s original size and the size of the finished product may affect the quality of the final print. Moreover, we currently do not have the tools needed for a professional cut, so the customer is responsible for the cutting of excess paper around their image. Refunds will ONLY be given if:
- we run out of print materials during a print
- our machine malfunctions
- there is a layout, positioning, or cropping issue
Pixel vs. Vector
Bitmap graphics are made up of coloured pixels. Pixels are very small rectangles of varying colours make up an image. The problem with bitmap graphics is that they don’t enlarge well in Photoshop. This can result in poor definition and low quality, depending on how much an image is enlarged. Common file formats for bitmap image data include GIF, JPEG, PNG, and TIFF.
Vector graphics, on the other hand, are not constructed with pixels. They are made up of mathematical expressions and instructions that produce lines, curves and filled shapes. Vector images can be scaled to any size without any loss in quality. Common file formats for vector graphics are EPS and AI.
Any image for a printing output of over 2ftx2ft should be at least 5MB in file size.
Common File Formats
BMP: a raster image composed of pixels
PNG: designed for transferring images on the Internet; does not require a patent license
JPEG: also used for publishing Web graphics. JPEG compression algorithms significantly reduces the file size of images; however high amounts of compression may noticeably reduce the image quality
TIFF: a high-quality graphics format often used for storing images with many colors, such as digital photos
AI: a vector image file created by Adobe Illustrator
EPS: may contain 2D vector graphics, bitmap images, and text
PSD: a file created in Adobe Photoshop
GIF: a common format for Web graphics, especially small images and images that contain text, such as navigation buttons
RGB vs CMYK
Red, green, and blue are “additive colors” (RGB). If we combine red, green, and blue light we’ll get white light. RGB mode is optimized for display on computer monitors and peripherals, most notably scanning devices.
Cyan, Magenta and Yellow are “subtractive colors” (CMYK). If we print cyan, magenta, and yellow inks on white paper, they absorb the light shining on the page. Since our eyes receive no reflected light from the paper, we perceive black.
Pixel Aspect Ratio (PAR) is a mathematical ratio that describes how the width of pixels in a digital image compare to their height.
Common aspect ratios in still photography include 4:3 (1.33) used by most point-and-shoot digital cameras; 3:2 (1.5) used by 35mm film, APS-C (”classic” mode), and most DSLRs; 1.81:1 (close to 16:9) used by APS-H high definition mode; 3:1 used by APS-P panoramic mode; and 1:1 (square) in a variety of cameras.
Common print sizes (in inches) include 4×6 (1.5), 5×7 (1.4), 4×5 and 8×10 (1.25), and 11×14 (1.27). Large-format cameras typically use one of these aspect ratios. If the images you need to print must be resized, please understand that by changing the aspect ratio, the image may distort and become stretched or too compact. Sometimes leaving the image the way it is is the best option.
