I Need To Know Petty

View:

If you are shopping for a good knife, there are a number of things you will need to know. Different types of knife blades have different flexibilities and strengths, for different uses and purposes. Make sure you take all of these factors into account if you are looking for the right knife for your particular situation.

A knife with a drop point blade will have a slow curve on the point, allowing a great deal of control for deep cutting. This increased strength will be important on a camping or hunting trip since you do not know what you may encounter on your trip, and you have to be ready for anything. If you are looking for a knife that is both easy to use and yet very powerful for cutting, the drop point blade is ideal.

A blade with a clip will allow even more control than the drop point blade for the user. The control in a clip joint blade also gives you a great deal more precision in addition to the control afforded, for whatever you are working on. Clip point knives have a curved belly that will make slicing more easy. The greater control and the slicing ability will allow for making cuts and adjustments with ease, features you may find very important in certain situations.

A Tanto blade will give you an incredible amount of straight and sharpness. The thick flat design of this blade, instead of being bulky, nevertheless gives a very sharp edge to the knife. This is because of the bottom edge and the obtuse point that the knife has. The Tanto blade is specifically designed to give great strength with an extremely sharp point.

A sheepsfoot blade is for anyone who is looking for a good slicing knife. A sheepsfoot blade will give a better slice than a knife with a clip point, and is especially meant for this use, slicing rather than cutting. The sheepsfoot blade is very popular among paramedics and other emergency responders since they can easily cut through a seat belt, without risk to the victim.

Dot gain (the amount a dot grows when printed on press) is caused by ink spreading as it is absorbed by the paper. To determine the amount of dot gain occurring, you need to know the difference between the tonal values as defined in the file/image, and the corresponding halftone dot size measured on the press sheet.

Measuring Dot Gain

Using a densitometer, dot gain is measured from the 50% patch of each process color on the press sheet's color bar. Dot gain is the net percent increase in a 50% screen. For example, a dot gain of 20% would be due to a 50% screen in the file being reproduced at 70% on the press sheet.

More dot gain occurs in midtones than in quarter and three-quarter-tones. Quater-tone dot gain results in a 25% screen printing at 40% or so; three-quarter-tone dot gain results in a 75% screen printing around 88%. The is good to keep in mind when evaluating tonal values in a 4-color image or graphic.

ICC Profiles

Photoshop automatically compensates for dot gain when an image is converted from RGB to CMYK for print production. How an image is converted is determined by the ICC profile that is selected. An ICC press profile is a file that characterizes the color capabilities (including the amount of dot gain) of a particular press/paper combination (i.e. web press/coated paper).

Coated Papers: It is recommended using the SWOP2006_Coated3v2.icc profile for converting RGB images into CMYK for those images printing on coated paper. The SWOP2006_Coated3v2.icc profile can be found on the official SWOP website (www.swop.org), in the Resource Center section (www.swop.org/resources/).

Uncoated Papers: For uncoated paper, we recommend using the U.S. Web Uncoated v2.icc profile, which ships with Photoshop.

Rather than using profiles, Photoshop's Custom CMYK Setup can be used to determine how your RGB images are converted into CMYK; however, doing so will not result in as good of a conversion as using an ICC profile. If your image has already been converted to CMYK using Photoshop's default color settings, it will still print okay since Photoshop will have used its default profile (U.S. Web Coated (SWOP) v2.icc) for the conversion.

Total Area Coverage (TAC)

In 4-color printing, if you adjusted the darkest area of your image to be 100% of each color (CMYK), you would have a TAC of 400%. In theory, this would result in a very deep shadow area; however, in reality, it would be a mess on press. Having too high of an ink coverage leads to problems such as ink contamination and drying problems. To avoid these problems the TAC for uncoated paper should not exceed 280% and 300% for coated paper. Each of the profiles recommended above use appropriate TAC limits as part of their characterization data set.
