We often receive images that are not reproducible as received. Maybe it’s a bitmap image that is highly pixelated at a low resolution. Maybe the only thing we have is a business card with a logo or a logo from a website or some other rendition of a design. In these cases, our client often expects us to do miracles.
One action that has proven somewhat effective in enhancing an image is a PHOTO-PAINT feature known as posterize. This can be especially useful if a photo is to be power traced into a vector image.
With the bitmap selected, click the edit bitmap icon. When the image opens in PHOTO-PAINT, go to image > transform > posterize; a dialog appears with a level slider. For this image, I chose (8) as the level. This essentially limits the number of colors to eight. It is good to enable the before-and-after view to monitor the changes visually.
When you are happy with the result, click OK and save. Close PHOTO-PAINT and the modified image reappears in CorelDRAW.
Fig. 1 compares the original photo with the posterized version. I selected the new posterized image and chose to trace it. Fig. 2 is the vectorized version — ungrouped, I deleted the blue background. One could easily select the resulting objects and give them each a fountain fill to suggest a more photo-realistic appearance while still retaining the vector object characteristics.
Dealing with poor-quality artwork is a challenge for any designer. Sometimes we succeed with minimal effort; other times, it is only an exercise in futility and frustration. We must educate our customers on what kind of artwork is acceptable for reproduction and what is not.
