Hallo! After asking some questions about installing metafont's, I have not made any progress. I would like to show the problem with J. Knappen's EC-fonts. To access this fonts I adapted my little typescript: -----------------type-kna.tex-------------------------- \starttypescript [serif] [knappen] [name] \definefontsynonym [serif] [ecrm1000] \stoptypescript \starttypescript [serif] [knappen] [size] \definebodyfont [5pt,6pt,7pt,8pt] [rm] [tf=ecrm0900 sa 1] \definebodyfont [9pt] [rm] [tf=ecrm0900] \definebodyfont [10pt] [rm] [tf=ecrm1000] \definebodyfont [10.95pt] [rm] [tf=ecrm1095] \definebodyfont [12pt] [rm] [tf=ecrm1200] \definebodyfont [14.4pt] [rm] [tf=ecrm1440] \definebodyfont [17.28pt] [rm] [tf=ecrm1728] \definebodyfont [20.74pt] [rm] [tf=ecrm2074] \definebodyfont [24.88pt] [rm] [tf=ecrm2488] \stoptypescript \starttypescript [Knappen] \definetypeface [Knappen] [rm] [serif] [knappen] [knappen] [encoding=ec] \stoptypescript --------------------------------------------------------------- and used the following testfile: --------------------tst.tex--------------------------------- \usetypescriptfile [type-kna] \usetypescript [Knappen] \setupbodyfont [Knappen] \starttext \chapter{Fest} Gottes. \stoptext ----------------------------------------------------------------- Problem: 'ecrm2074 at 600', which exists, should be used! 'ecrm1200 at1036.8' is used instead! How can this be corrected? Thank you for your help! Wolfgang
