Disclosed is an ink jet recording method by ejecting microscopic ink droplets, and curing the ink via actinic radiation. The ink contains pigment dispersion including photopolymerizable compounds and pigments, hydrophilicity &#x3b4;m of the surface of pigments incorporated therein being at most 22 cal&#xb7;cm.

Ink jet recording method, pigment dispersion and actinic radiation curable type ink jet ink composition

The ink jet recording method ejects an actinic radiation curable ink having a cationically polymerizable component from an ink jet recording head onto a recording media, and subsequently cures the ink by exposing it to actinic radiation. The ink in a recording media satisfy the formula (|C&#x2212;B|) of 0&#x2013;20 mN/m in which C is the surface tension of the recording media in mN/m and B is the surface tension of the cured ink in mN/m after exposure to the actinic radiation.

When an incoming call has been received, caller identification sent from a network is detected by a caller identification transformer unit, a MODEM unit and a CPU. A predetermined information unit included in the caller identification is displayed on an LCD. Whether or not an answer to the incoming call is to be made, the predetermined information included in the caller identification is stored in an incoming-call journal data memory unit as incoming-call journal data. The incoming-call journal data is automatically printed out by a printer unit as an image at a predetermined timing.

The improved method of development is implemented with an automatic processor for developing presensitized offset printing plates with a substantially virgin aqueous solution that contains an alkali silicate and that is supplied for each printing plate, said aqueous solution containing calcium ions in an amount of up to 10 mg/L. The improved developing apparatus comprises a means of mixing a concentrated developing solution with diluent water to prepare a working solution and a means of applying the working solution onto the surface of a presensitized offset printing plate being transported. The apparatus is characterized by further including a mechanism that performs ion-exchange on the diluent water before it is mixed with the concentrated developing solution.

Method and apparatus for developing presensitized offset printing plates

A developing solution of an imagewise exposed, presensitized offset printing plate is disclosed. The developing solution has a pH of at least 12.5, and contains a low content of a silicate in an amount of up to 1.0 wt % as SiO.sub.2, a surfactant in an amount of 0.01 to 10 wt %, an aromatic carboxylic acid in an amount of 0.1 to 10 wt %, and an amine compound represented by the following general formula (I) in an amount of 0.1 to 10 wt %:

Method of developing presensitized offset printing plates and developing

Disclosed are a method and an apparatus for processing with a developing solution repeatedly used, both an imagewise exposed, positive-working presensitized lithographic printing plate and an imagewise exposed negative-working presensitized lithographic printing plate. The plates each comprise an aluminum support and a light-sensitive layer formed thereon. A replenishing solution is added to the developing solution to compensate for the degradation of the developing solution brought about by development and/or by carbon dioxide in the air. The method comprises the steps of; measuring a reflection density of the light-sensitive layer of the printing plates to discriminate the type of the printing plate, selecting a predetermined developing condition according to the discriminated type of the printing plate, and developing the printing plates according to the selected developing condition.
