Why is the raster to vector conversion necessary before printing?

Graphic designers and embroidery digitizers often handle clients who wish to enlarge a photograph or business logo for embroidery. If you do not have any experience in graphic designing, you might start thinking about the variance between these formants. Here’s a look at the main points of difference. 

  • What are raster graphics?  

Also referred to as bitmaps, raster images consist of pixels of colors that create an image altogether. It’s more like a pointillist painting consisting of individually colored paint dots.

The individual dot appears just like a colored point but turns into a detailed painting when combined with multiple dots. The same is the case with pixels in a raster image. Thus, a raster image shows rich details and enables users to carry out pixel-by-pixel editing. These images can be ideal if you wish to create digital paintings using GIMP or Photoshop programs. 

Raster images present complex, multi-colored visuals. Raster image files can be optimized for web usage and compressed for storage as well. Digital cameras create images only in this format. They can be in PNG, GIF, or JPG form. 

The quality of such images relies on the overall dimensions of the image and the number of pixels-per-inch. Images with greater PPI and dimensional measurements are of high quality. When it comes to printing projects, images need to be of at least 300ppi. 

  • Why convert images to vectors? 

If you have a blurry image, artwork, or logo, raster to vector conversion is absolutely necessary. 

Vector images can be resized (larger or smaller) infinitely, without impacting the image quality. No matter if you increase or decrease the size, printouts will be just as precise. And unfortunately, this is not the case with raster images, as they lose their quality if enlarged. 

Vector images are the only option for sign jobs as signs are large, and vector images enable artist to create better quality images despite the increase in size. 

  • Infinitely scalable

Vector images are infinitely scalable. Put simply; you can turn a vector graphic small or large without worrying about losing quality while doing so. And that’s the reason they are used the most by digitizers. 

Artist and designers working on a raster image need to work on missing colors and fill gaps in the missing colors after enlarging the image. On the other hand, there’s no such guesswork involved in vector graphics, no need to fill any gaps. Thus, logos are often saved in vector format to be digitized or printed (billboards or posters) in any required size, shape. 

  • Editing flexibility

Designs created with Photoshop can consist of multiple layers. If you save such data as a raster file (JPG or PNG), it gets flattened as layers are merged into one. It becomes challenging to get those layers back and edit them. On the other hand, a vector file saves layers as per their original shape. They can be recovered at a later stage using Adobe Illustrator.

  • Handling the conversion 

As there are various methods for raster to vector format conversion, these processes vary dramatically. No software can offer 100 percent accurate conversion. A simple online Jpeg to SVG converter may not prove helpful. The crucial aspect is that only highly experienced professionals can convert a raster image into a vector one. Thus, human intervention is vital for high-quality format output.
