Are room temperatures and humidity a factor in controlling print quality?
2.g Temperature and humidity can definitely affect printing success. Again, the reasons for ingredients to alter dry time as required. Normal environments I have encountered during the years were generally 65-75°F and 45-55% R.H. I have been in a plant where the product was extremely hydroscopic, and required the R.H. to be a maximum of 17%. I have also been in places such as Puerto Rico, Korea and China, where the R.H. sometimes approached 85-90%. If the inks are developed properly, all of these conditions can be dealt with easily. Another factor is air movement within an area. Direct exposure to heating, air conditioning and ventilation ducts will accelerate drying of the ink, and cause premature loss of critical solvents.
