Title: black percentage help please
Post by: sportsshoppe on August 03, 2018, 11:18:10 AM
I received this file to print and its an PDF, when I import to Corel and try to convert to black it gives a transparency which prints out half tones. I also have to add outline on some of the words. Can anyone convert image to black and white for me with no background  Thanks

Here it is converted to black and white with a green background and the transparency removed.

For some reason the transparency is still there when I downloaded the file :-\

Looks like all the black was at 1,1,1 rgb and 90% opacity. I changed to 0,0,0 and 100% opacity.

No problem. In Illustrator I deleted the white, deleted a clipping mask that didn't really serve a purpose, locked the background. Select all (because it appears actually all the blacks had varying opacity), then changed to 100% opaque, 0,0,0.

When I look at the original file, I see an image that has intentionally varying shades of black/gray text.
I feel some elements are supposed to be more prominent than others.

As for the file the SPSI created...you have lost all of the white elements of the original image.

Maybe I am way off on this, but it is what I would interpret in my shop.

Best of luck.

There are a lot of different transparency values for the black, on the white text as well.

We get a lot of files from "artists" that have more than one of any color, 3 or 4 blacks, assorted blues and reds when there should only be one. These "artists" simply aren't aware of what's needed for print production, and go about it any way that works on their monitors. The first thing we would do in Illustrator is select a single black element, the "select same fill color" from the Select menu. Surprise, surprise, surprise, not all the black elements are selected. Once that's determined, all of them are then made the same black, no transparency at all, 100% pure, no tints. Then, we add in tints as necessary, if necessary. This is done for each color, and the "artist" is informed and billed for it. For this image, we'd have one black for the bold text, one black for what appears to be a 5% to 10% ribbon background, and a white.
