Hi, I know the latex 360 is sold as a safe machine with no ventilation, which I accept, but when pvc vinyl and pvc banner etc. is printed on and heated to say 90 degrees, does it not give off harmful fumes. Appreciate the commments : )

As with all equipment installations, to maintain ambient comfort levels, air conditioning or ventilation in the work area should take into account that the printer produces heat. Typically, the printer's power dissipation is 4.6 kW (15.7 kBTU/h) for HP Latex 360, 2.6 kW (8.9 kBTU/h) for HP Latex 330 and 2.2 kW (7.5 kBTU/h) for HP Latex 310. Air conditioning and ventilation should meet with local environmental, health and safety (EHS) guidelines and regulations. Consult your usual air conditioning or EHS specialist for advice on the appropriate measures for your location.
For a more prescriptive approach to adequate ventilation, you could refer to the ANSI/ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) 62.1-2007 Ventilation for Acceptable Indoor Air Quality. As an example, a minimum exhaust rate of 2.5 L/s.m² (0.5 cfm/ft²) of fresh make up air for "copy, printing rooms" is specified.
Special ventilation equipment (air filtration) is not required to meet U.S. OSHA requirements on occupational exposure to VOCs from water-based HP Latex Inks. Special ventilation equipment installation is at the discretion of the Customer. Customers should consult state and local requirements and regulations.
Please note that the ventilation and air conditioning units should not blow air directly onto the printer.
So as long the printer meets the ventilation requirement described above, you shouldn't have any problem.
Please keep us inofrmed about the situation.

Thanks for the reply, but this is more aimed at the inks rather than the material. I am just wondering if HP take into account what are safe levels of heating PVC, which I am not sure of. In unventilated rooms are the fumes coming off the material harmful at that curing temperature?.

PVC supports quite high temperatures for printing. This shouldn’t be the problem.
This mist that you are talking about it is most commonly seen where warm, moist air meets sudden cooling between printer and environment.
