Therefore, if you converted an image with complex colors into vector then you will have a large number of separate vector entities in your image, rather than smooth, solid lines, text, and polygons. Reducing colors is important because a conversion engine will detect every shade as a separate region in the image. This gives you the clearest possible contrast between the background (typically white) and the foreground (typically black – these being the elements you wish to vectorize).Ĭommonly, however, even an image that appears black and white may be formed of hundreds of colors on the grayscale. In an ideal world, all images that you’re converting to vector would be monocolor (black and white). If your image has a particularly low DPI you can increase the scale in Scan2CAD (by clicking Raster Effects > Scale). For best results, we recommend an image resolution of at least 300 dpi. The rule of thumb is that lines should be 4-5 pixels thick. Secret tricks of the trade? Right this way… These guys have road-tested every tip on the Internet and even incorporated them into the Scan2CAD raster-to-vector conversion engine. Here, Scan2CAD’s in-house experts weigh in on the 10 most essential raster tips that everyone should master. It is common that some level of ‘cleaning’ will be required for the raster image before you put it through the conversion process. While it can seem simple at times, it’s not really a one-click process. Raster-to-vector conversion is often billed as the easiest CAD process to learn – just upload the file, click a button and out comes the perfect vector drawing. Vectorization means your image becomes easily editable at any scale. Step 2: Go to the overhead menu and select Effect > Document Raster Effect Settings.It’s easy to see why people want to convert from raster to vector. Step 1: Place and embed your image in Adobe Illustrator. Usually, the resolution of screen images is 72 ppi, you can change it to 300 ppi to enhance the image quality. Method 1: Change ResolutionĪs I briefly mentioned above, when you sharpen an image, it enhances the image quality, so changing the resolution of your image is one way to do it. Windows or other versions can look different. Note: all screenshots are taken from Adobe Illustrator CC 2022 Mac version. The minimum requirement, let’s say, when you zoom in to 100%, the image shouldn’t be pixelated. Important note: for the best result, the image you want to sharpen should be a high-quality image. Try the image trace option if you’re sharpening a vector image, and try to change the resolution if image quality is your concern. In this tutorial, I’m going to show you how to sharpen an image using Image Trace and changing resolution. If Adobe Illustrator is the only option, depending on your image, you might not get exactly what you want. It took me hours to research and come up with a couple of imperfect solutions that can be helpful for what you’re looking for. The best and easiest way to sharpen an image is doing it in Photoshop, but I understand that not everyone uses Photoshop. Sharpening an image means increasing an image’s quality by enhancing the definition of an image’s edges, and that’s NOT what Adobe Illustrator does! Not going to lie, I didn’t know the answer to this question.
