Reflective Security Signs

Wednesday, August 11th, 2010

The typical road sign such as warning, informational, and speed signs are manufactured with traffic and engineering grade reflective sheeting. The reflective properties are achieved using beads of glass that will reflective light from any angle. The road signs would be considered the high end of the reflective sign products.

There are two types of plastic security signs, the first a non-reflective, the second, is a reflective security sign. This article will highlight only the reflective security signs.

The reflective security signs are not to be confused with self- luminous materials. Reflective materials require light to illuminate or reflect. These signs are similar to the road signs we all observe while we are driving. The reflective materials used to manufacture a reflective security sign also employ the glass bead to reflective light.

The yard security sign is the best advertisement for the home owner, because the sign communicates to a potential burglar that this house is protected. Since most criminals are opportunistic and will gravitate to the path of least resistance. These home thieves’ will not attempt a B&E because of the security devices in situ in a home. Most burglars’ do not want to be caught they will move on to a home that does not have a security system.

The reflective security sign continues to advertise after dark that a home has a security system. The potential home invader then chooses a home without a security system to burglarize. The reflective security sign increases the security customers’ peace of mind.

There are two schools of thought of how a reflective security sign should be printed. The first idea states, that the sign must be printed with transparent inks, so the entire sign reflects light. This is similar to how road signs are printed; the whole sign reflects when automobile lights illuminate the sign.

The second proposal of how reflective signs should be manufactured. The inks on the sign should be opaque. The areas of the sign without ink will reflect the lights of an automobile.

The background of the sign would be printed, utilizing opaque inks. The letters or words of the sign would be reflective as they are reversed out of the opaque background. The following is an example of this process. If a sign had the imprinted message, HOME SECURED BY ABC SECURITY, only the words, HOME SECURED BY ABC SECURITY, would reflect the illumination of cars lights. The background of the sign at night would be invisible.

Both printing paradigms are valid, and will convey the message desired, by the security company and the home owner.

If I had to choose I would rather have a reflective security sign protecting my home.

Brewing Beer Process Continued

Monday, August 2nd, 2010

Brewing beer is an interesting process.  Basically what you are trying to create is an infection in the beer.  I will explain about that later.

The night before brewing, I had to cold steep coffee in other words I had to take my ground coffee add cold water to it and let it sit overnight.  Then the next day we added that coffee mixture to the water.  Because the coffee has certain oils in it, it will actually kill the head of a beer.  So as part of the grain mixture we had to add carapils.  These make the head frothier to counteract the oils in the coffee

You start off with 6 gallons of purified water (which gets boiled off to 5 gallons).  Once you bring the 6 gallons to a boil you start adding the ingredients.  The first thing you have to do is add the barley grains.  You can use wheat but for my brew we used barley.  You use a grain bag which is essentially a mesh bag you use to put the grains in and steep the grains.  Much like you would steep a tea bag in a hot cup of water.  However this cup is 6 gallons.  After the water has cooled down to 170 degrees you put the grains in the bag and you steep them for about 20 minutes.  Basically you are adding the grains for color and flavor only.  You are not extracting sugar from the grains with the steeping (which is called mashing).  The reason you are not extracting the sugars is because I bought a recipe that had an extract in it.  Once you add the extract the mixture is now called the wort.

Once the extract is added then you bring the wort to boil.  Then once the mixture is at a rolling boil you start a timer for 60 minutes and you add the hops.  When you add hops this early in the boil you will not get any of the aroma or the flavor.  These are called the bittering hops.  They add bitterness to the beer.  The reason these are bittering the beer is because all of the boiling you have to do is extracting the alpha acids out of the hops.  Once you add those hops it gets boring because you are just letting the wort boil.

Just before the boil ends I had to add the lactose (which is milk).  I wanted to brew a coffee milk stout so I have to have lactose in there. Now the lactose has to be un-fermentable sugars because I wanted the milk taste in the beer.  I did not want the yeast to eat the lactose sugars.

Once the boil ends things get very fast and interesting.  You have to take the wort off of the burner and you have to put a wort chiller in the wort.  Basically it is a heat transfer system.  It is a very long copper tube that is twisted around and around in a circle and goes in the wort.  You run cold water through it and the cold water cools down the wort, to the point where it is safe to pitch (add) the yeast.  Basically you have to pitch the yeast at a certain temperature.  Too cold and the yeast takes longer to get active.  Too hot and the yeast dies.  You want to infect the wort with the yeast ASAP.  Basically you are infecting the wort with the yeast so that nothing else can infect the wort.

Once the wort is chilled, you transfer it to a car-boy.  A car-boy is a 5 gallon glass bottle.  Up until this point it has been very easy to keep things sanitized because everything that you are working with is at a boil so anything that got in there was killed instantly because it was boiling.  Now that we are no longer boiling it can get infected very easily, and everything must be sanitized.

Once the wort is transferred to the car-boy you pitch the yeast.  What the yeast is going to do is eat all the fermentable sugars and poop alcohol, and fart CO2.  That is how the beer gets its alcohol content.

That is basically how you brew a coffee milk stout.  Or at least it was my observation of the whirlwind of activity in the process of brewing beer

Fading of Color Printing

Thursday, July 29th, 2010

What You Did Not Know to Ask

 

First we must set a baseline for the discussion about the fading of color printing. Fading of color is a dilemma common to all industries. The plain truth is all color fades. Products such as carpeting, cars, decals, signs, banners, and a host of other products printed or pigmented with color fade.

The question we need to ask, “How quickly does a products color fade?”  This answer to this inquiry depends on the method of how a product is tinted.

The product that is pigmented implies the product’s color  is imbedded into the substrate. The pigmented product such as carpeting fades very slowly, but the product still fades. The product that is painted such as automobiles also fades gradually, but still fades.

The products that are printed such as decals, banners, signs, and other products exposed to sunlight. The process of printing these products utilizes two methods of printing, digital and screen-printing. The other methods of printing such as, flexography, offset will not be considered. These techniques are exclusively for indoor use.

I will highlight one product line, the plastic security sign. The plastic security sign is printed using the screen-printing method of printing. This technique is extremely fading resistance, but as noted before everything fades.

The question again, “How quickly does a products color fade?” The answer to this query depends on a few factors. The security lawn sign printed correctly will never fade to white. The printed colors will lighten over time, red may morph to an orange, dark blue may lighten.

The factor that lengthens or shortens the fading effect of a security sign is placement. The sign that is mounted facing north will not have significant color modification for five or more years. The security sign that is placed on the southern exposure will see color transformations in shorter durations. The east and west placements also have varying times of color degradation.  

Little known fact

Screen-printing companies test the veracity of their inks, by placing the security sign on a test board facing south. Every month a sign is left on the test board is equivalent to four months of sun exposure.

To conclude plastic security signs will not fade to white. Color changes will occur differently due to sign placement. So the question,” How long will my plastic security sign last”?  The answer is a general between 3-10 years.
