Abstract
A drying device, which dries a photosensitive layer of a photosensitive planographic printing plate using infrared rays, includes an infrared emitting device and a filter that is arranged between the photosensitive planographic printing plate conveyed through the drying device and the infrared emitting device and that blocks a predetermined range of wavelength. More specifically, the filter is arranged between a web that is conveyed through the drying device and a mid-infrared radiator, so as to block 30% or more of wavelengths of 1 μm or less. As a result, fogging on a photosensitive coating layer can be prevented, and high heating efficiency can be achieved.
Claims20
A drying device that dries a photosensitive layer of a photosensitive planographic printing plate using infrared rays, comprising:
- an infrared emitting device;
- and
- a filter that is arranged between the infrared emitting device and the photosensitive planographic printing plate as conveyed through the drying device and that blocks a predetermined range of wavelength.
A drying device that dries a photosensitive layer of a photosensitive planographic printing plate using infrared rays, comprising:
- an infrared emitting device;
- and
- a filter that is arranged so as to be separated by a predetermined distance from the infrared emitting device and that intercepts infrared rays emitted from the infrared emitting device to the photosensitive planographic printing plate as conveyed through the drying device,
- wherein the filter blocks wavelength in a predetermined range, of the infrared rays.
A drying method for drying a photosensitive layer of a photosensitive planographic printing plate using infrared rays, comprising:
- drying the photosensitive layer using a drying device in which a filter that blocks wavelength in a predetermined range is arranged between the photosensitive planographic printing plate as conveyed through the drying device and an infrared emitting device.
A drying method for drying a photosensitive layer of a photosensitive planographic printing plate using infrared rays, comprising:
- emitting infrared rays whose maximum energy wavelength is within a mid-infrared range (2 to 4 μm) via a filter to the photosensitive planographic printing plate as conveyed through a drying device so as to dry the photosensitive layer,
- wherein the filter blocks wavelength in a predetermined range, of the infrared rays.
