PANOSE is a type of classification system, which attempts to find a close substitution for a missing font. I don’t use this very much, so I’m not sure what effect it has on the issue at hand. but I don’t suspect it’s very much if anything at all.
Corel is not finding the font which was used even though it is there.
A couple of reasons might explain why…
1)- is that the FontType between what Layout used, and what Corel is looking for are different.
2)- It’s not locating the font by it’s unique individual name. (…or, possibly not searching the correct folder ??)
3)- as an outside guess (which probably isn’t the case here) confusions of this sort can happen when there are a lot of installed fonts to choose from. By a lot I mean several hundred, and if you had than many of them you’d probably already know about the nature of this problem. so back to points 1, and 2 for now.
Below are some comments which I was writing earlier in the night. I held off on them because I didn’t want to jump too far ahead too early, and didn’t want to add in any confusion. At this point they go to support the ideas from points 1, and 2, and hopefully paint a clear picture of how thing can get messed up all these different Font options.
The Font names that you mention… ‘ArialMT-Identity-H’… are the ‘Real’ names of the font.
And are describing a particular variation which might differ by weight (stroke thickness), or angle, or some other unique characteristic which distinguishes it from its larger group affiliation to the Font-Family called ‘Arial’. (other varients exist as well… bold, italic, Ariel Narrow bold, Ariel Narrow italics and so on).
A professional quality font-family might have a dozen or more unique variations to choose from. The fonts that get included into the OS will usually be a small set of options, and they’re not always of a high quality. Design programs such a Illustrator, or inDesign, or possibly even Corel will often install a wider sampling of professional grade fonts and this stis very well with the graphic designers, and typographers who use this software. They like the extra options and slightly better quality where it exists.
The other part of this is that there are also different Font Types. and you’re not currently being able to see what those are.
In general you’ll see two main options…
TrueType Fonts .ttf
OpenType Fonts .otf
…but there a few others as well, mostly older font formats that don’t often get included with the modern OS’s, or software packages. You’d more likely run across them If you’ve downloaded a lot of fonts from the internet, especially the free offerings.
Now while it shouldn’t work like this, and I can’t explain why sometime it does… If Layout is specifying a font of one variety, and of a specific type, BUT Corel is expecting to see something slightly different (in either type or variety) that could be cause enough for not opening a file, or flagging it as a corrupted one.
If the file was corrupted, I wouldn’t expect to open on my end. But since I CAN view it, that corruption warning seems questionable. ??
