fonty Type 1 vs. Type 1C

[Vojtech Hala]

Dobry den,
chci se zeptat, jaky je rozdil mezi fonty Type 1 a Type 1C ("Compact Font
Format"). Totiz zda se mi, ze dokument je o hodne hezci kdyz pouziju pdfTeX
nez kdyz prevadim dvi->ps->pdf, a chtel bych vedet proc je to tak, pripadne
jak prevest DVI na PDF tak, aby vypadalo stejne hezky. (psfonts.map jsem
vygeneroval pomoci skriptu updmap s volbou type1_default=true)

Acrobat Reader mi o fontech z pdfTeXu rika, ze Encoding je Built-in,
zatimco u vystupu z dvipdf je Custom. Co to znamena?

A jeste dotaz k vystupu z pdffonts. Co znamena tech 6 pismen na zacatku
radky? Manual rika, ze to je "subset prefix" - co si pod tim predstavit?
Proc jsou prefixy v tech dvou PDF ruzne? Podmnoziny fontu by mely byt
stejne, kdyz je stejny zdrojak. Souvisi to s typem fontu?

Tohle mi program pdffonts po prevodu z DVI:

name                                 type         emb sub uni object ID
