Control Of A Four-Color Lithographic Press By Monitoring The Hue Consistency Of The Reproduction With A Densitometer, Chikashi Hashimoto

Theses

The purpose of this study was to establish a reliable control method to maintain the visual hue consistency of "critical colors" on a four-color lithographic press. The term "critical colors" indicates those colors which are deemed by the customer or pressman to be important for a particular job and will require special attention to maintain their hue consistency. It was hypothesized that a densitometer, which automatically computes hue error and grayness using the Preucil method, could be used to measure critical colors and maintain their computed hue consistency. In order to analyze the effect of the control method monitoring hue …

Adsorption Capabilities Of Adsorbents For Selected Toxic Air Pollutants, Richard Michael Vaccaro

Theses

The relative adsorption capacities of seven toxic, volatile organic air pollutants of either proven or suspected carcinogenic potential were tested on various adsorbents. Tests were run at flow velocities similar to those set in field sampling. This allows for extrapolation of test results to actual ambient air sampling systems. Experimentation was performed using a gas chromatograph (G.C.) equipped with a flame ionization detector. Sample introduction was carried out using the "displacement method" where the sample is introduced to the adsorbent cartridge as a plug.

Incipient elution volumes (V_N), normalized for bulk adsorbent packing volume, were obtained at various …

Electric Field Enhancement Of Efficiency In Autoradiographic Exposures, Harvey Smith

Theses

An external electric field was applied during autoradiographic exposures in an attempt to influence the path length and trajectory of image forming beta particles. Various techniques were employed to maximize the electric field applied. No evidence was found for increases in efficiency of image formation within the receiving emulsion, up to a field strength of 7 x 10 volts/cm.

Studies On The Lith Development Of A Silver Iodobromide Emulsion, Larry Zurbrick

Theses

The lithographic development of a silver iodobromide emulsion with thiocyanate substituted for bromide in a lith developer formulation showed differences in behavior with regard to induction time and maximum rate of development at equal levels of normality. An experiment was designed with development time, halide concentration, and exposure level as the variables with maximum rate of development, time to reach 0.20 optical density (induction time), and slope at 0.40 optical density as the response parameters. The maximum rate of development with the developer containing bromide was found to be significantly dependent upon exposure level and not significantly dependent upon bromide …

The Effect Of Photographic Reducers In Autoradiographic Intensification Method For Image Recovery Of Incorrectly Exposed Radiographs, Donald Vachon

Theses

Autoradiographic image intensification methods for recovering the images of underexposed step wedges, resolution targets and radiographs were investigated. The fog level of the intensified image was decreased by treating the film in a subproportional photographic reducer (mixture of potassium ferricyanide and sodium thiosulfate) prior to activation with S-35 thiourea. The fog level of intensified images of a step wedge decreased from a density of 1.32 to .12, the maximum contrast increased from 2.08 to 5.52, the relative speed increase calculated at 0.6 above fog level increased from 3.05 to 4.06 while resolution remained the same at 5.0 lines per millimeter.Radiographs …

The Role Of Reliability In The Publisher/Supplier Relationship In Textbook Production, Steven Brenner

Theses

Most publishers in the textbook publishing industry experience production delays. If the delays are serious it could result in a postponed publication date. The ramifications of a postponed publication date range from anxiety to the author and publisher to lost revenues. Most textbook publishers are required to have their new texts reviewed by adoption committies, therefore it is imperative that their books be ready by a certain date. There are many functions involved in the book making process. A delay in any one area may hold things up in other areas, thus compounding the situation. The purpose of this thesis …

Continuous Fractionation Of Protein Mixtures By Ph-Parametric Pumping, Yuk-Wei Wong

Theses

Continuous pH-parametric pumping separations of a haemoglobin - albumin - CM Separose system were experimentally investigated. The parapump system has a feed, containing the protein mixture to be separated, introduced alternately to the top and bottom of the chromatographic column. The top and bottom products are withdrawn from the apparatus during the bottom and top feed respectively. It is shown that under certain conditions the pH-driven parametric pump has the capacity for removal of a protein component from one product fraction and large enrichment in the other fraction. Moreover, the continuous process can be operated with a large feed throughput.

A Study Of The Effect Of Coating Variations On Tone Reproduction In The Association Products Plate, Mark Woodhouse

Theses

The halftone process is so much a part of printing today that it is often hard for printers to conceive of the notion of reproducing an image without a screen. Before the idea of breaking up an image into small dots came along however, printing was being done with lithographic methods which produced excellent results and the main concern of the theorist and technician was how to produce a more consistent, higher-quality, continuous tone image. Perhaps it is unfortunate that the advent of the halftone process distracted thought from this area to such a large degree, since it wasn't until …

A Low Frequency Sine Wave Camera, Russell Palum

Theses

An optical system using spherical and cylindrical optics can convert area-modulated spatial sinusoidal targets to intensity-modulated spatial sinusoidal images. A specific system was analyzed with a spot diagram. System response to 30 cycles-mm~l is predicted. The system mechanical tolerances were determined on the basis of modulation transfer function (MTF) calculations. A mechanical structure which would maintain these tolerances was designed and built.

The Modification Of Simple Images By Fourier Transform Manipulation, Noel Chavez

Theses

Knowledge of how an image is changed by a given modification of its Fourier transform is important when attempting to find solutions to problems in image processing. Several types of filters were used to modify the Fourier transforms of an edge and a bartarget. The images were reconstructed from the modified transforms to determine the change produced by a given modification. Various regions of the Fourier transform determine specific characteristics of the image. The amplitude of the low frequencies controls the form and average level of the image, while the amplitude of the high frequencies effects sharp transitions and noise.

Design And Evaluation Of A Stepped Diaphragm Intensity Scale Graphic Arts Sensitometer, Patrick Meehan

Theses

An Intensity Scale Sensitometer for testing the photographic response of Graphic Arts materials was built and evaluated. The sensitometer utilizes a stepped area diaphragm and a cylindrical lens to produce a stepped illuminance distribution at the film plane. Both tungsten and pulsed xenon lamps are provided. A computer aided study was used to find the optimum lamp position with respect to the reflector. A scanning aperture type shutter located at the stepped diaphragm and a knife edge aperture located at the lens are used to control exposure duration and intensity. The main advantage of this sensitometer is the production of …

Determination Of The Chemical Spread Function Of Kodak High Contrast Copy 5069 Emulsion, J.N.A. Laitre

Theses

A new procedure for obtaining the Chemical Spread Function of an emulsion-developer combination is discussed. This procedure consists of directly measuring the Optical Modulation Transfer Function (MTFO) by scanning the sinusoidal object irradiance distribution through the non-developed emulsion using a microdensitometer. The Modulation Transfer Function (MTF) of the processed emulsion is determined in the conventional manner. Then the Chemical Modulation Transfer Function (MTFC) is determined from the linear relationship: MTF = MTFC X MTFO. Once the MTFO is determined then the Spread Function is calculated using the Fourier Transform operator. Photographic systems are in general non-linear. However it is well …

The Effects Of Sulfur Sensitization And Stabilization By 4-Hydroxy-6-Methyl-1,3,3a,7-Tetraazaindene On Hydrogen Sensitization Of A Photographic Emulsion, David Lyon

Theses

Hypersensitization using H2 gas is the most recent addition to the techniques available to reduce the effects of low intensity reciprocity law failure. Because of the presence of addenda in all commercially available emulsions, the interactive effects of hydrogen sensitization with a common stabilizer (4-methyl-6-hydroxy-1,3,3a,7-tetraazaindene) and a common form of chemical sensitization (Sulfur Sensitization) alone and together were investigated. A primitive, single jet emulsion was coated with and without the above addenda. Samples were paired and either treated to a hydrogen baking process at 65°C for 20 minutes, or left untreated. Sensitometric exposures were made in a room air environment …

Image Quality Dependence On Partial Coherence In A Projection Printer, Bruce Radl

Theses

A study has been made of the printed images from a projection printer whose light source can be varied to provide illumination of various levels of partial coherence. The coherence interval for five light source configurations was measured with a shearing interferometer at the object plane of the printer. Many test images were made with the printer for each of the five degrees of partial coherence and results showing image quality as a function of coherence interval have been reported. It was found that with an 11µm coherence interval the image forming characteristics were typical of an incoherent instrument and …

The Effects Of Polyethylene Oxide On Dmaac's "B" Type Developer, Harold Mccullough

Theses

This report describes the results of a study comparing ASA speed, contrast index, and resolution from a developer time series. The time series was made on six levels each of PEO-400, -600, -1000, and -1500 added to DMAAC's "B" developer. Kodak's SO-277, low contrast, and SO-243, high contrast, aerial duplicating films were used. Results show that PEO-400, at a concentration of 30ml/l, can be a material help in getting higher speeds and contrast index from SO-277 aerial duplicating film without loss of resolution.

Comparison Of Bromide, Benzotriazole, And Phenyl Mercaptotetrazole And Their Effect On Photographic Development, James Kretchmer

Theses

A comparison of three commonly used antifoggants was made. Their effect on the formation of fog and image density development was studied using a rate factor of development. This rate factor is defined as the slope of the curve for density-log development time. Bromide and benzotriazole were found to have no effect on the rate of development whereas 1-phenyl-5-mercaptotetrazole was found to significantly reduce the rate of development. Bromide and benzotriazole were found to cause a suppression of image density only by increasing the time before density formation begins.
