摘要:
A system has been described for reading out stimulable phosphor screens, plates or panels, whether or not differing from each other in phosphor composition or phosphor layer arrangement, after exposing said screens to X-rays. Said system comprises at least one source of stimulating radiation, an array of transducer elements arranged for detecting light emitted upon stimulation and for converting said light into a signal representation of said image. Said system further comprises filtering means for preventing light, emitted by said source of stimulation light, from being detected by said transducer elements, wherein said filtering means transmits light with a high transmission efficiency for emitted blue light upon stimulation and low transmission for radiation from the stimulating laser source.

摘要:
A method for making a flexographic printing master includes the steps of providing a flexographic printing support: applying image-wise on the flexographic printing support subsequent layers of radiation curable liquid by an inkjet printing device whereby one or more applied layers are immobilized using a curing device before one or more subsequent layers are applied, such that a relief with a top hat profile is obtained; and grinding the relief so that the height DT of a top hat segment is reduced. An imaging apparatus includes structure to perform the above method.
摘要:
A method for making a flexographic printing master includes a first step of providing a flexographic printing support; a second step of applying image wise with a first resolution a layer of a radiation curable liquid partially covering the printing side of the support; a third step of flood exposing the applied radiation curable layer to fully cure the layer; and a fourth step of image wise laser engraving the cured layer with a second resolution which is higher than the resolution of the second step. An imaging apparatus can perform the above method.
摘要:
A method of coating a peripheral surface of a sleeve core with a radiation curable coating liquid including the steps of: supporting a sleeve core in a vertical position coaxial with a coating axis; providing an annular coating collar, supplying the coating liquid to the annular coating collar and moving the annular coating collar along the sleeve core in a vertical direction coaxial with the coating axis, thereby coating a layer of the coating liquid onto the peripheral surface of the sleeve core; wherein the coated layer of the coating liquid is cooled by the peripheral surface of the sleeve core to have a viscosity at the temperature of the peripheral surface of the sleeve core and at a shear rate of 10 s−1 which is larger than a minimum viscosity ηmin, with: η min = d 2 50 wherein d represents the thickness of the coated layer expressed in μm, and ηmin is expressed in mPa·s. Also, a coating device for performing the above coating method.
