Remembrance Day

Monday, November 5th, 2018

As we approach Remembrance Day we are proud to have duplicated many DVD’s and CD’s dedicated to the many who lost their lives in the Two World Wars and in other conflicts around the world.

We support Help For Hero’s and salute all those who fought to make the world a better place; and for those who still defend us in the Armed Forces.

Recycling /Upcycling,

Monday, June 4th, 2018

If you care about ecology and the careful and efficient use of our worlds resources you will be interested in reading read this article.

We have always viewed our general efficiency, in all aspects of our work as part of being an eco-friendly and responsible British Company. This includes the responsible choice and use of our own suppliers and supplies, careful budgeting and careful use of power (mainly electricity) and associated machinery. In addition to this we have internal policy regarding the recycling of any waste material.

This article is an informal piece about our most recent thoughts and practices.

From the start we use high quality casing for our Cds,Dvds and Blu-rays with the philosophy that in the long term these will provide the best protection for your discs and although some are plastic, will last a life-time so do not need to be replaced. This is slightly counter culture in what has become a throw away society in many walks of life, but there is common sense in choosing quality which will last; and despite this we still remain one of the cheapest, if not the cheapest for all of our products. There is a great deal of inferior quality, cheap packaging out there that is never use for any of our customers.

Over the 12 years that we have been in the duplication business we have noticed a large shift in the casing that our customers choose for their orders. From the days where nearly all CD’s were packed in a plastic standard jewel case and all DVDs packed in a Amaray plastic DVD cases, we now find that a much larger percentage of customers choose the more eco-friendly options of card wallets/digi-paks.

The card/paper we stock for all our printed parts is FSC Certified and sustainable. We feel this is a better option than recycled paper as research shows that due to the high volumes of bleach used to whiten the paper this is not as environmentally friendly…..which is not good. Responsible sourced and properly managed paper is a green industry, encouraging the growth of trees in the worlds forests. www.fsc-uk.org

In addition our, experience and the feedback our customers give us tells us that paper based products are less susceptible to damage in transit and less costly to courier, deliver and store compared to plastic cases.

Customer choice is highly important to us however and whilst there is a demand for the plastic standard jewell and standard DVD case and we continue to provide these on our web-site.

A large part of our recycling programme is to reuse all the incoming boxes and packaging to supply our out-going parcels.

Protecting orders is our top priority so this comes first however where possible we re-cycle all cardboard, jiffy/mailite bags and packaging, always removing any personal information on them first.

Good House-keeping in the production room means less waste, however on every order we do produce 1 or 2 over-runs of discs. This enables us to keep a control copy here of every order. We have researched widely the re-cycling of CD’s, DVD’s and Blu-Rays and have yet to find a highly sustainable channel for these.

We do however supply unburned discs to artists and students of design free of charge for sculpture or artistc projects.

There are also an increasing number of designers who use discs as the raw materials for projects like garden mosaics, lamps, dishes, picture frames, flower pots, mirrors, coasters and even a disco ball!! See www.zerowasteweek.co.uk for DIY ideas on how to recycle discs.

Another great use for discs is as bird scarers on allotments, they catch the sun if hung and will deter without harming birds who would eat delicate crops.

We minimise the use of paper by having an efficient invoice emailing and chasing system; although we will always send hard copy invoices if requested. We shred all paper that we can and this is re-used for animal bedding and then composted.

In short we view ourselves as a very eco-friendly company and we constantly update and re-visit our processes to see where we can improve and evolve in a productive and conscientious way.

Gained knowledge and know-how is the key here to keeping an efficient and eco-friendly approach in balance for our industry.
 

The Blu-Ray

Thursday, March 15th, 2018

The Blu-ray Disc founder group was started in 2002 by MIT and nine leading Electronics Companies: Sony, Panasonic, Pioneer, Phillips, Thomson, LG Electronics, Hitachi, Sharp and Samsung Electronics.

 

The name is taken from the blue laser that is used to read from and record to a Blu ray disc, the blue laser allows for a much higher density and hence a larger storage capacity and so the Blu-Ray disc is a digital optical disc data storage format.

It was designed to supersede the DVD format, and is capable of storing several hours of video in high definition (HDTV 720p & 1080p) and Ultra High Definition Resolution (2160p).

Although the Blu-Ray disc looks exactly the same as a DVD in size and shape there are many differences between media including storage capacity,laser technology and disc construction,image resolution and player compatibility.

The Blu-Rays storage capacity is measured in gigabytes (GB), like computers and ipods.

Storage Comparison:

DVD Single Layer: Can store about 4.7GB data which is about two hours worth of movie at Standard Definition…these are commonly referred to as DVD 5’s.

DVD Dual Layer: Can store twice the amount of data at 8.7 GB which equals about four hours of movie at Standard Definition ….these are commonly referred to as DVD 9 ‘s.

Blu-Ray Single layer: Can store approximately 25Gb data, this equals about 2 hours of High Definition Information or 13 hours of Standard Definition Information.

Dual Layer Blu-Ray :can store about 50GB data which is about 4 hours of High Definition Information or 26 hours of Standard Definition.

Laser Technology

Lasers are used in both DVD and Blu-ray technology .As the disc spins the laser reads the information stored on the discs and transfers both the picture and the sound to the television.

DVD: DVD players use a red laser at 650nm wave length to read DVD discs

Blu-Ray : Blu-Ray players use a Blue laser to read the stored information; the wave lenghts are shorter than the red at 405nm and are smaller in diameter, this allows for a closer and more precise reading of the information on the disc.

Disc Construction:

Physically DVD and Blu-Ray discs are the same in appearance:both have circular tracks on their bottom layer that enables the laser to read information stored on the spinning disc.

The tracks on a DVD are much further apart than on the Blu-Ray; you will see that it follows from this that the amount of information that can be stored on each type of disc is different; the Blu-Ray having the far greater storage capacity.In short a Blu-ray can squeeze about 5 times as many tracks onto the same size disc as a DVD.

Both DVD and Blu-Ray have a protective layer designed to resist scratching; the Blu-Ray in addition has a hard coating that makes it more scratch resistant.

Image Resolution

This is measured by the number of vertical lines times the number of horizontal lines of light in a picture.It is represented by the number of horizontal lines going across the screen like 480, 720 or 1080.The higher the number, the higher the resolution the more detailed the picture you see.

DVD: Almost all DVD’s have standard definition of 480 or enhanced definition of 520.This look ok on a standard television,utilising all the available pixels on the screen. If however this is blown up to a large HDTV the picture may look grainy.

Blu-Ray: The Blu-Ray was designed for the high definition 1080 display….since they can store 25 GB data you can fit a whole High Definition movie on a single layer. Blu-Ray currently has the best image resolution on the market and looks amazing on HDTV, they are one of the only sources that display in 1080.

Player Compatibility:

Happily Blu-ray Players support DVD’s and the image will be decent but obviously not the high definition quality of a Blu-ray.

Due to the  larger lasers used in DVD players they it cannot read the tiny grooves on a Blu-ray disc.

In short you can play a DVD in a Blu-ray player but you cannot play a Blu-ray in a DVD player.

 

Lastly and very importantly Blu-Ray can handle 4K (Ultra HD)...we don’t need an new type of disc for our new TV’s; you can have it all with the Blu-Ray !
