IMHO lack of film and paper emulsion thickness is the biggest source for people to start or prefer photogravure processes. If printing paper was many times thicker and if it would be tanned to match with carbon or photogravure print , there would be no alternative processes industry. Same thing is for film , pyro developers are expensive and harmful but people starts to use it after spending couple of years with photography for few microns of tanning.

I thinked that double side emulsioned film,glass and printing - inkjet,gravure,emulsion, carbon added heat recess polyurethane or silkscreen- on double side of transparent propylene - bopp - film for backlit or reflectance is an alternative to above problems.

Is it tried before ?
