There are many instances when a raster file can be used, but we still prefer vector, and the more files you open the more you will start to see what will work and what won't. Say they send a file at 6"圆" and 600 PPI, you can scale this to 10"x10" and 150 PPI and the file is usable. If an image is smaller than the size they want it printed but 600-1000 PPI you can typically scale it to print size and lower the PPI and the image will be useable. A vector file is a graphic based on mathematical curves and paths instead of pixels, like a company logo made in digital illustration software. A raster file is made up of square-shaped pixels, like a photo taken on a digital camera. If you open your image and it is on a huge canvas like 100" x 100" but only 100 PPI you can scale down the file to print size and change the PPI to 300 and the file would be usesable. Luckily, there are only two image file types you really need to know about: raster files and vector files. Raster files consist of tiny pixels and have a set size and resolution. There are many raster files we can work with, but knowing from the beginning will help speed production down the line rather than having to ask for new or better files. There are two basic file types: raster (or bitmap) and vector. Ideally you'll get a file that is to size and 300 PPI. What to look for is an image to the proper print size 8" x 8" in this case and at least 150 PPI Navigate in the Menu to Image < Image Size. That will bring up an Image Size menu, switch your dimensions to Inches. Once you have your file open in Photoshop, navigate in the Menu to Image < Image Size. Therefore, the user must decide which one is suitable. Vector graphics are assigned a mathematical expression that the design program reads and uses to create the visual form of the shape.
VECTOR AND RASTER FILES ARE SOFTWARE
Vector graphics are illustrations created using design software (such as Adobe Illustrator) and can be scaled larger without any loss of quality.
Both types of engravings have their distinct appearance, features, pros & cons, and limitations. Raster and vector are two forms of digital graphics. Raster engraving and vector engraving are the two types of engravings done using a laser engraving machine. To use a raster file preferably it is to the size it needs to be printed, and at 300dpi. Comparison Table of Raster vs Vector Raster, Vector Raster images are also known as Bitmap images and are made up of small dots known as pixels. What's the difference between Raster and Vector Images In this video, we'll break down the main differences between what the two image. Beginner's Guide on Raster and Vector Engraving. You zoomed in and you have a raster file? No problem, often times we can still use them.
