PDF was a proprietary format controlled by Adobe until it was released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008, at which time control of the specification passed to an ISO Committee of volunteer industry experts. In the early years PDF was popular mainly in desktop publishing workflows, and competed with a variety of formats such as DjVu, Envoy, Common Ground Digital Paper, Farallon Replica and even Adobe's own PostScript format. The PDF specification also provides for encryption and digital signatures, file attachments, and metadata to enable workflows requiring these features.Īdobe Systems made the PDF specification available free of charge in 1993. PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content), three-dimensional objects using U3D or PRC, and various other data formats. The last edition as ISO 32000-2:2020 was published in December 2020. PDF was standardized as ISO 32000 in 2008. PDF has its roots in 'The Camelot Project' initiated by Adobe co-founder John Warnock in 1991.

that won't work even though photoshop is included in that suite. eg, using a cs6 suite serial number with a photoshop cs6 installation file. ie, you can have a valid serial number, but if it's for program A and your installation file is for program B, you will see an invalid serial number message.Ĭommon mismatches are language/region (eg, serial number is for western europe and installation file is eastern europe), platform (eg, serial number is for a mac and installation file is win), license type (eg, education vs enterprise vs individual).Īnd one of the most common is using a program installation file with a suite's serial number. Assuming you're using a valid adobe serial number (6 groups of 4 numbers), you have a mismatch between your installation file and serial number.
