Not a good idea to have Book and Regular in the same family, as both have "400" as their weight number.

Hi Nick (happy new year btw),

I made sure the weight where all different (made a mistake it's Text not book). The weights of the fonts are 400, 500, 600 and 700.

This is likely a Font Naming issue.
(BTW, the thread's title is misleading.)

"Not a good idea to have Book and Regular in the same family, as both have “400” as their weight number."

This conflates two separate issues:

1) All different weights in a family should have different values for usWeightClass. There are other potential complications with usWeightClass: see my first post in this thread (with the big chart)... http://typophile.com/node/16327

2) InDesign (only) has some issues with families that have multiple fonts that it considers to be "regular" weight, which includes the name "book" among others. See my and Miguel's posts in this thread: http://www.typophile.com/node/35394 (where I again explained that this was a separate issue, despite Nick's belief that one was causing the other problem)

Cheers,

If I manualy enter different weight values, wouldn't that solve the problem?

Nick’s belief that one was causing the other problem

My "belief" is correct, as an observation of the way that FontLab assigns 400 to both Book and Regular, in the first page of its Font Info dialog. I'm also aware of the problem with InDesign, but didn't mention it (I try to avoid criticizing Adobe).

Thanks for clarifying the issue, with links, Thomas.

Happy New Year, Martin!

Yes, FontLab assigns 400 to both, but that's easily overridden manually (as Martin thinks), and doesn't cause any problem other than poor sorting of styles within some Adobe apps.

But the reason I mention above is a much stronger reason not to have Book and Regular in the same family, which does not have any workaround, let alone a trivially easy one.

Cheers,

T

seems to be working fine, thx for the help!
