For our print methods we ideally prefer to use artwork created in Adobe illustrator (AI) or similar programs that can create vector graphics or file types like SVG (Scalable Vector Graphic) or EPS (Encapsulated PostScript). As we use large format printing, trying to increase the size of a small image may lead to poor quality printing.
Vector or Raster
Vector – These types of images are broken down into separate objects (which can be called shapes). These are scalable without compromising on the quality of the image. No matter how much you enlarge it will not lose quality.
Raster – Raster image files are as follows: BMP, TIFF, GIFF and JPEG (or JPG). They are normally larger in size than vector graphics. These are harder to enlarge whilst keeping the same quality, as trying to modify them can result in a loss of quality. For example if you were to zoom into a JPEG you will start to notice pixelisation and a lack of quality.
Bleed is an area of the print that is cut off to create the final artwork in print form. This helps allow for any movement in material, inconsistencies in design, cropping, trimming or sewing. Our standard bleed for all our designs is 35mm on all sides. This is because we are creating large format prints and a 35mm bleed will ensure that artwork is cut correctly to ensure no visible unprinted areas.
Check the quality of artwork
For PC - If you already have a JPEG you can check the size and dpi of this quite easily. On a windows computer you just need to right click on the image, then click on Properties and then click on the Details tab. This will display all information regarding the image. If it was created using Adobe Illustrator or Photoshop these would normally contain information regarding its DPI and the physical dimensions of the image.
For MAC - If you already have a JPEG you can check the size and dpi of this quite easily. On a Mac you will need to open the image in the preview application. Once it has been open click on tools and then show inspector. This will provide you with all the information you need to know about the image. It will include DPI and the physical dimensions of the images.
