What's the difference between photogravure and rotogravure?
Photogravure
Definition:
(n.) A photoengraving; also, the process by which such a picture is produced.
Example Sentences:
(1) Four years later, when I drew my first pay from a newspaper, I discovered that the Glasgow Herald had not one but two shipbuilding correspondents, who shared a room and wrote long pieces for the paper's annual commercial and industrial supplement, which used photogravure for its colour cover and inside contained official photographs of ships on their trials, always side-on and moving right to left, with a crisp, white bow-wave and the Argyll hills in the background.
(2) Using cytogenetic analysis of peripheral lymphocytes the authors examined three groups of subjects: 42 rotogravure printers exposed to toluene in concentrations of 400-4400 mg.m-3 for a mean period of 13 years, 28 administrative employees of the printing plant exposed to low concentrations of toluene (8-16 mg.m-3) in their offices, whereby more than half of them spent on average two hours in the photogravure workshop, and 32 control subjects.
Rotogravure
Definition:
Example Sentences:
(1) Eighteen of the rotogravure printers and one of the referents were heavy drinkers of alcohol.
(2) The printers had been exposed to solvents for 9 to 25 years during employment at flexo and rotogravure printing plants, while the controls had no history of solvent exposure.
(3) One hundred and sixty rotogravure printing workers exposed mainly to toluene are compared (clinical examination, liver and kidney tests) to 38 unexposed workers.
(4) Neurotoxic effects of toluene were examined in 43 male rotogravure printers exposed to toluene (age 27-63, mean 41 years; duration of exposure 11-40, mean 22 years) and 31 male offset printers of the same age with slight exposure to aliphatic hydrocarbons.
(5) Exposure to toluene in two publication rotogravure plants was investigated to examine how accurately long-term exposure can be estimated on the basis of production rate.
(6) The high incidence of aberrations could be explained by the exposure to toluene, but the influence of rotogravure printing dyes cannot be excluded.
(7) The rotogravure printers performance was inferior to the referents in tests measuring visual cognitive abilities.
(8) In 1985, 30 rotogravure printers exposed to toluene for 4-43 years (median 29) were examined by means of interviews and psychometric testing.
(9) Visual evoked potentials (VEPs) from stimulation by checkerboard pattern reversal were examined in 54 rotogravure printers exposed to toluene (all men, aged 22-64 years, duration of exposure 1-41 years).
(10) In a cross-sectional study of 181 male workers of a rotogravure printing plant, most of whom were exposed to toluene levels well above the GDR threshold limit values, 55 subjects revealed pathological liver screening values (activities of serum aspartate aminotransferase, alanine aminotransferase, gamma glutamyltransferase; liver size).
(11) Toluene exposure was studied in 62 male rotogravure printers, employed in three plants.
(12) Using cytogenetic analysis of peripheral lymphocytes the authors examined three groups of subjects: 42 rotogravure printers exposed to toluene in concentrations of 400-4400 mg.m-3 for a mean period of 13 years, 28 administrative employees of the printing plant exposed to low concentrations of toluene (8-16 mg.m-3) in their offices, whereby more than half of them spent on average two hours in the photogravure workshop, and 32 control subjects.
(13) Forty-three male rotogravure printers with long-term toluene exposure and 31 age- and sex-matched offset printers without toluene exposure were examined in detail.
(14) Chromosome analyses were carried out in peripheral lymphocytes of 27 workers exposed to toluene in a rotogravure plant.
(15) In 28 office and technical employees of the same plant, more than half of whom worked 2 h daily in the rotogravure workshop, an increased percentage of aberrant cells and chromatid breaks was also found.
(16) A cohort of 1020 rotogravure printers exposed to toluene and employed for a minimum period of three months in eight plants during 1925-85 was studied.
(17) A psychological test battery was administered to a group of 43 rotogravure printers exposed to toluene (mean age 41 years, mean duration of exposure 22 years) and to a referent group comprising 31 offset printers of the same age.
(18) Four groups of workers of the rotogravure, shoe and plastic industries, all exposed to toluene, were studied by the authors.
