Printing on Matte or glossy Digital Photo Printing Paper

When printing digital photos you have a selection between matte and slick photo prints. slick photo prints have a shiny discontinue while matte ones have a more subtle neutral one. So which one should you choose? There is no right answer - there are pros and cons to both.

Matte and slick are two dissimilar finishes to the photo paper digital photos are printed on. Using dissimilar chemicals and processes photo paper can have a slick or a matte finish. slick discontinue looks shiny, reflects light very well and looks vibrant and color rich. Matte discontinue on the other hand does not reflect much light and looks "darker" and duller.

There are pros and cons to selecting whether matter or slick digital photo prints. Here are some of them:

Printing on Matte or glossy Digital Photo Printing Paper

Glossy photo prints: slick photo prints are shiny and are more animated to the eye. They look fancy and transport a high ability feeling. slick photo prints have vibrant colors. Colors also look rich and deep on slick photo prints. On the downside slick photo prints "shiny" attribute can be a problem when photos are viewed using intense light sources such as daylight sun or strong light bulbs. Light reflected from the photo print can blind the viewer manufacture it hard to see the photo. slick paper is also more likely to attract dust and fingerprints and is thus more likely to get dirty over time. Black and white slick photo prints do not look as good as matte ones.

Matte finish: Matte photo prints do not reflect light and are thus easier to view at almost any light condition. Matte photo prints are also less likely to attract dust and fingerprints and are less likely to get dirty over time. Black and white matte photo prints look better than black and white slick photo prints. On the downside matte photo prints do not have the fancy high ability look that slick photo prints have. Colors in matte photo prints are less vibrant and less rich than on slick photo prints.

So which one to pick - matte or glossy? It honestly depends on your needs and what you are going to do with the photo prints. As a general rule use slick photo prints for color prints and matte photo prints for black and white ones. If the photo prints are going to be touched by many habitancy and used a lot matte is a better selection unless you do not mind spending time cleaning your slick photo prints every now and then. Also if you plan to print large photos (for example to hang on the wall or frame and put on your desk) matte is a better selection since a large slick print would act as a large slick and shiny light reflector.

As with many other choices a matter or slick selection is a matter of personal preference. To make an educated decision you should have experienced both. If you do not have that caress you can pick a few photos some color and some black and white and print them both on matte and on slick paper and in dissimilar sizes. Look at the prints and see what you like and what you do not like about them. In the hereafter you would be able make better choices by applying that experience.

Testing Scr - How To Test And Check Silicon Controlled Rectifier

Testing Scr (silicon controlled rectifier) can be done by using an analog multi meter or specialize tester (such as the Peak electronic atlas component analyzer) designed to check semiconductor devices easily. Scr can be found in many electronic circuits. Part numbers such as the For3G and Mcr 100-6 were very common used in computer monitor. Some called Scr as thyristor but in actual fact the word thyristor should not be related exclusively with the silicon controlled rectifier. It is in fact a normal name given to all four layer Pnpn devices along with the generally used Scr. The diac, the Triac, and the Scs are the other popular devices belonging to the house of thyristors.

Scr consists of three pin of Gate (G), Anode (A) and Cathode (C). In order to recognize the pin out, one must find it from semiconductor data book such the preeminent Philips Ecg master semiconductor replacement guide. The data book will list out the normal specification of the Scr such as the volt and ampere. If you want to know more details about a singular Scr, you can all the time try to quest from the internet. Normally the Scr manufacturers will provide the full datasheet for those who want it.

Once you know the pin outs of the G, A and C legs you can begin to test the Scr. If you have the Peak electronic atlas component analyzer tester, what you need to do is to associate the three small clips to each pin of the Scr (any part number will do). The tester will begin to analyze the Scr and prompt you with the display such as "Sensitive or low power thyristor" before it tells you the exact pin outs of G, A and C. After the first test, the tester will at last show you the respond at the Lcd display. Red is Gate, Green is Cathode and Blue is Anode. It is a uncomplicated process and you will know the respond in less than 10 seconds. If there is a question in the Scr, the tester would not be able to show the results instead it shows a shorted reading.

If you don't have this tester for checking Scr, I'm showing you an additional one easy way on how to test Scr fast. You need an analog meter set to X1 ohm. Place the red probe to the Cathode and black probe to the Anode pin. At this time the meter doesn't show any reading. Now moderately move the black probe and touch the Gate pin (the black probe still touching the Anode pin) and you will observation the meter's pointer will kick as shown at the photo (low resistance).

Removing the black probe from the Gate pin (the black probe still touching the Anode pin) you would noticed that the resistance continues to be there (low resistance). This is due to the conduction of Scr as the meter battery is Normally able to provide current more than the keeping current. If at this stage you removed the black probe from the Anode pin and associate it back, the pointer will dropped back to infinity (high resistance). If the Scr could hold the resistance then the Scr is carefully good. If it can't hold then the Scr is faulty.

Conclusion- convention testing Scr more often to see how's the follow like. Try some distinct part numbers and power Scr-and if the resistance don't hold using X1 ohm, you may try X10 ohm and etc.
