Frequently Asked Questions
No, it is a very rare and largely obsolete technical term from photomechanical printing.
No. That would be incorrect and confusing. Use 'two types', 'both types', or 'a pair of types' instead.
Yes, but very rarely. It means to reproduce an image using the duotype printing process.
Historically, it allowed for a printed image with greater tonal depth and richness than a standard single-plate halftone.
