colour intensity and dots

Postby Pedroski » Mon Feb 09, 2015 9:51 am

I'm trying to copy a document to save flying home and a long wait to get an official copy. I thought it would be easy!
I scanned the document in at the highest resolution I could, 1200 X 1200 dpi to a .png. The (large) light blue letters of the scan (approximately: colour a5bbffff, size 56) show up as a series of blue dots, interspersed with the white of the paper, when viewed at 100% zoom, but the dark blue letters are solid colour, not dots, the white of the paper cannot be seen, which is producing the rich navy blue colour I want. Maybe the original document was printed on a different kind of printer. I just have an Epson L351 inkjet.

I thought maybe I could get the colour I want by printing the dark blue letters on 2 or more layers and offsetting them by, say, a pixel, to fill the gaps.

How can I best get a solid blue colour fill for a large letter?

Would have been better to scan to OCR and let Open Office read the document.
Try grayscale - if the letters are vector graphic you'll always be able to set the color afterwards.
But maybe the document is a picture with letters on it?

Might be better to use GIMP for raster/bitmap operations, unless you have intentions of adding vector elements.

But I'm confused... the dark blue text is described as already solid, without gaps.

Is a solid light blue desired? The proper color might be captured by using the eyedropper tool. That color can fill traced paths or typed text.
Have a nice day.

I can't get the size and distribution I want in OO or Gimp or Inkscape as pure text. When I put the character spacing at 8.5 Pts, one word matches up exactly, but the others are pushed too far. I will copy the scanned text from the .png scan as a path, then I will have the exact same text as a vector object. Somehow the scan is many times bigger than the A4 page, probably because I scanned it at such a high resolution.

The font is like Verdana or Vemana2000, but the B is rounder at the bottom, not flat at all, and the t has a sloping top. The other letters are the same as Verdana. Since it is about size 56, you notice it.

I have the correct colour for light blue, a5bbffff matches exactly, just the dark blue will not come out right. I'll keep trying.

The eye-dropper can pick up the dark blue colour, but then it does not print the right colour. I set the Document Properties colour management to BestRGB

To identify the font itself you have to create an image file with black text on white background and upload it here:

Is it a free font you might be able to find it at www.dafont.com .

The font/word spacing can probably be resolved with the Text toolbar widgets for, well, letter and word spacing.

If one or two characters are slightly different, they can be converted to paths and their shapes can be manipulated. Or, those characters might be found in other typefaces.

Thanks for the tips. I used gimp to copy the text, I created paths for each letter, then changed them to selections, filled the selection. I am getting pretty close to what I want now.

Hey that what the font is really cool! Looks like I need Adobe Myriad Pro Bold! Thanks very much!
