-- What is a vector image or vector artwork?
Vector graphics have the unique advantage that may be scaled up or down to any resolution with no aliasing or any other distortion. This way you can maintain the quality of the vector image no matter how many times you enlarge it. As long as the structure of the vector image is preserved with lines, curves, and polygons, it is extensible to an unlimited size. When a vector image is saved in a raster format, it loses this quality.
Vector graphics are commonly found today in the SVG, EPS, PDF, AI graphic file formats, and are intrinsically different from the more common raster graphics file formats such as JPEG, PNG, APNG, GIF, MPEG4.
-- What is a raster image or raster artwork?
A raster graphics or bitmap image is a dot matrix data structure that represents a generally grid of (points of color), viewable via a monitor, paper, or other display medium. Raster graphics are best used for non-line art images; specifically digitized photographs scanned artwork or detailed graphics. However, because raster images are pixel-based, as opposed to vector, they suffer a malady called image degradation. Just like photographic images that get blurry and imprecise when blown up, a raster image gets jagged and rough. To maximize the quality of a raster image, you must keep in mind that the raster format is resolution-specific — meaning that raster images are defined and displayed at one specific resolution. Resolution in raster graphics is measured in dpi, or dots per inch. So when you decide to buy a raster image, it is important that the image size is as large as possible and that it contains at least 300 dpi. Overall, as compared to vector graphics, raster graphics are less economical, slower to display and print, less versatile, and more unwieldy to work with. Remember though that some images, like photographs, are still best displayed in raster format. Common raster formats include TIFF, JPEG, GIF, PCX, and BMP files.
-- I would like to print a graphic product at home. What do I need to pay attention to?
If you bought a product that is in raster form and ready to print, then you need to make sure that the color scheme of the product is CMYK and that the product is made in a resolution of at least 300 dpi. If you bought a product that is in vector form then pay attention only to the color scheme. If you do not want to change the product and want to print it as it is then paying attention to the size of the product, width, and length, for example, Letter, A4, A3, and others. The size of the product must match the format you want to print. If you are good at manipulating images (in raster or vector form), then you can adjust the purchased product so that the colors and quality of the product in printed form will be as similar as possible to the desired one. Usually, the product description says it is ready to print.
-- Why do the printed colors look different from the colors on my screen?
Basically, printers and monitors produce colors in different ways.
Monitors use the RGB (red, green, blue) color model, which usually supports a wider spectrum of colors. Printers use the CMYK (cyan, magenta, yellow, black) color model, which can reproduce most—but not all—of the colors in the RGB color model. Depending on the equipment used, CMYK generally matches 85–90% of the colors in the RGB model.
When a color is selected from the RGB model that is out of the range of the CMYK model, the application chooses what it thinks is the closest color that will match. Programs such as Adobe Photoshop will allow you to choose which color will be replaced. Others may not.
The quality of the monitor and printer are also very important factors. Of course, the better the quality of the printer, the greater the chance that the image on the screen will be very similar to the printed form. Of course, you can also improve the quality of the printed product with the right choice of paper. Select the paper according to the desired effect of the printed product.
-- Why are products in the RGB color scheme?
Some products are in the RGB color scheme because the RBG color scheme offers several different color shades. The colors are fuller and more vibrant. All products can be used for any purpose in electronic form and the monitor showing the colors in the RGB color scheme retains the colors when the image is displayed on the screen. As soon as the color scheme of the product is changed to CMYK, a lot of vividness and a lot of color shades are lost. If you do not want to display the image in electronic form, you can still convert the image to a CMYK color scheme, but the colors will no longer be the same.
-- What is a Bleed?
In printing, bleed is printing that goes beyond the edge of where the sheet will be trimmed. In other words, the bleed is the area to be trimmed off. The bleed is the part on the side of a document that gives the printer a small amount of space to account for movement of the paper, and design inconsistencies. It should be created at least 3mm in size on all edges where the bleed is needed.
Our products are always made with the extra edge seen in PDF files. If you are printing a product at home and do not want additional edges or trimming, we suggest that you print a JPG or PNG image, which (one of them or both) are also included in the package for each product. JPG or PNG is just a product image with no additional safety bleeds and in our case contains at least 300 dpi.
