Flash cards or Memory card. What are their purpose.?

Memory card (also known as flash memory card, flash memory card or flash memory card) is a small portable data storage device widely used in various electronic devices to store almost any data: photos, videos, music, documents. , games and programs. It is basically a chip (a set of electronic circuits) that can be written and rewritten multiple times.

USB flash drives vary in shape, size, storage and compatibility. They can be used as primary data storage or to expand the storage capacity of devices such as mobile phones, laptops, tablets, digital cameras, camcorders, drones, MP3 players, consoles, printers and more.

How are memory cards different from other storage devices?

Flash cards are small (mostly no bigger than a thumbnail) and easy to use. Unlike hard disks (HDDs), memory cards have no moving parts and are therefore considered much more resistant to mechanical shocks and temperature fluctuations. However, they are not as durable as USB sticks because they do not contain plastic or rubber.

The flash memory card can also be easily removed from the electronic device. However, compared to a USB memory stick that is inserted directly into a USB slot, a memory card usually requires connecting it to a computer using a card reader.

Although some modern electronic devices such as laptops or tablets come with built-in card readers, most require an external card to access data on a computer’s flash memory card. On the other hand, USB flash drives are compatible with all devices that have a USB port, while USB memory cards cannot be inserted into any of your devices because different devices usually accept different types of memory cards.

What are the main types of flash memory cards?

In recent years, the choice of USB memory cards has narrowed significantly due to standardization. Currently, the most common are SD memory cards, Memory Stick and CompactFlash. They also have more or less popular sub-varieties (for example, for Memory Stick memory cards, they are Memory Stick Duo, Pro Duo, Pro-HG Duo and Micro M2). And the least common but still used are xD Picture Card, MultiMediaCard (MMC) and SmartMedia.

 The first type in the list, SD or Secure Digital, has already become an industry standard. SD cards are used by more than 400 brands and are found in more than 8,000 electronic devices. They come in different abilities, speed classes and shapes.

Memory Stick was invented by Sony and can be found in devices released before 2010. CompactFlash was designed specifically for digital cameras and is the type of card used in high-end single-lens DSLR cameras today.

In general, each device is compatible with a certain type of memory card. However, some of them may have a universal slot or even several slots for different USB memories.

What is the differences between miniSD, microSD, SDHC, SDXC and SDUC?

With a wide range of sizes, capacities and models, SD memory is used in almost every type of device, from digital cameras to MP3 players. Currently, users can choose between the following SD memory cards:

• miniSD, which are based on SD technology but are smaller than standard SD memory cards. These are typical for portable devices such as smartphones and MP3 players, and are usually sold with a special adapter that allows them to be inserted into a standard SD card slot.

• microSD (also known as T-Flash and TransFlash), which are even smaller than miniSD and have almost replaced them in smartphones and tablets;

• SDHC/microSDHC (Secure Digital High Capacity) with file system and#40;FAT32and#41; differs from standard SD cards (FAT16) and has a capacity of up to 32 GB;

• SDXC/microSDXC (Secure Digital eXtended Capacity), up to 2 TB capacity and exFAT file system by default;

• SDUC/microSDXC (Secure Digital Ultra Capacity) with exFAT and high capacity up to 128 TB.

In terms of compatibility, older generation SD slots are not compatible with new generation memory cards such as SDHC, SDXC or SDUC. However, most SDXC cards are backwards compatible with SDHC card slots, which in turn accept SDXC cards if they are pre-formatted to FAT32.

Note that some SDXC compatible slots are programmed to handle 32GB and larger exFAT cards and may not accept SDXC cards reformatted to FAT32. The writing speed of SD memory cards also varies:

• Class 2 – of 2MB/s;

• Class 4 – of 4MB/s;

• Class 6 – of 6MB/s;

• Class 10 – of 10MB/s.

And another variation of the classification of SD memories: according to the read/write speed, the cards of the new generation (of SDHC) are divided into UHS-I (Ultra High Speed) up to 104 MB/s, UHS-II up . up to 104 MB/s p. 312 MB/s, UHS-III up to 624 MB/s and SD Express up to 985 MB/s.

The role of a digital printer

It is clear that digital printing has many benefits, but that does not imply that it is always the best choice for all formats. For example, this type of printing spoils faster than offset, does not accept metallic inks or UVI finishes and, of course, Pantone color specifications.

Knowing the characteristics and all the options for each project makes it possible to choose the one that is really advantageous. That is why it is important to rely on the experience of professionals who can individually assess each job. At Loyal Print we have a team of printing experts who advise our customers on the solution they need to make their projects a reality.

When we talk about digital printing, we refer to the process of direct printing from a digital file to any type of material (paper, vinyl, fabrics…).
Differences between digital and offset printing

A clear example would be printing a document or image with a laser or ink printer.
First of all, we must define what offset printing is in order to compare them. Offset printing is an analog and indirect printing process . This means that, in order to print any element, it first has to be created on a matrix plate and then transferred to a rubber support.
By not requiring a matrix plate, digital printing offers high production agility and flexibility. In addition, it does not require drying or cooling times of the material.
Another difference between digital printing and offset printing is the range of materials and formats that it offers us (different colors, textures, measurements, etc.). This allows you to have great freedom when creating communication, advertising and point-of-sale (POS) material.
The last difference that we will name, but therefore not least, is the impact it has on the environment . Thanks to the maximization of the performance of digital printing and low consumption of resources, it is less polluting and has a lower ecological impact, highlighting the LATEX technology that does not generate polluting waste and is respectful with the environment.
The maximum definition and sharpness of the print is achieved due to the rapid drying and as a consequence of the low ink absorption by the material. With this new technology, a high quality and durability of the products is guaranteed both inside and outside. 100% ecological process , these inks do not contain mercury or lead, do not emit volatile chemicals and do not generate ozone.
advantages of digital printing
Here are some of the advantages of digital printing:
• Flexibility and low volume: by not using plates such as offset printing, it allows printing few units. A very interesting advantage for SMEs that do not need large print runs and seek to manufacture promotional material at a low cost.
• Low delivery times: without a doubt, it is the most agile and quick option to have available products such as flyers, vinyl, printed fabrics, etc.
• Personalization: the trend in recent years is to offer increasingly personalized and unique products. Thanks to digital printing we can vary the pattern, material and design with great ease.
• No stock (Just in Time): As we have mentioned in previous advantages, the agility of production allows adjusting the volume according to orders.
• Variety of supports: One of the differences with offset printing and at the same time advantage of digital. The variety is infinite: textiles, vinyl, PVC, rigid supports, packaging…
types of digital printing
Within digital printing, there are 2 types: the small and the large format.
small format printing
It is the most used format, but it has disadvantages such as not having a 50×70 format.
large format printing
The large format is ideal for large projects or for companies looking to create materials and products for their marketing campaigns (especially at the point of sale).
large format printing
We are a distributor of materials for digital printing, signage, graphic industry, decoration and technical offices.

Advantages of digital printing over other systems

When printing a photo or text at home, digital printing is used because the file is not processed, it goes straight from the computer to the paper. The printer does all the work, it does not need an intermediate material as with offset plates in traditional printing. This makes it possible to apply it to all types of materials, not just paper, making the process simpler and making it available to everyone.

Digital printing can be done by inkjet or laser. The former requires cartridges and the latter toners, both options that surely sound familiar to those who have a printer at home or at work. In an industrial printing company specialized in graphic arts like ours we also use them, but on a much larger scale because we print thousands of papers.

The printing machine head moves by drawing horizontal lines at high speed and at one time for all colors, as opposed to four-color printing where the same paper or support is printed four times, resulting in a much slower process. It also differs in that the paper does not come into contact with the machine because there are no plates. Even so, the separation of inks is maintained and it is necessary to have several cartridges or toners to ensure a good quality in the final result when the original has some colors more used than others.

Digital printing can be used in large format, but it is the best option for small format, for example for calendars, notebooks, diaries, stickers, flyers or any corporate stationery.

What are the advantages of using a digital printer?

In our experience as digital printers, this type of printing has several advantages over others, although perhaps the most important is its low cost for low volume and urgent projects. Although, logically, it varies depending on the order.

Here are the benefits most valued by our customers:

Varied supports and finishes: as we have advanced, digital printing can be applied to paper as well as to fabrics, adhesives or vinyls. In addition, it accepts textures, prints and finishes that cannot be achieved with other types of printing, which makes it very eye-catching.

Flexibility:

since it can be used on any support, it offers a wide range of options that give a great deal of freedom to customize the final result. Thus, companies can take advantage of all their creativity to gain impact in their advertising actions.

Direct printing:

this is one of the characteristics of the digital file, which does not need anything physical or analogical. This makes it more economical because there is no need to invest in creating plates that increase production costs.

Agility in the start-up:

as it is direct printing, it is easier to start the project because it is not necessary to prepare plates or make proofs to adjust the colors. This makes it possible to accept orders that respond to quick actions.

Reduced delivery times:

digital printing is faster than offset printing also because the paper does not have to dry each time and can be cut and handled earlier. This means that deliveries can be made more quickly, which is very practical for small projects that require short lead times.

Small print runs:

digital printing is more efficient than other options because a cost per printed page is established. This makes it very advantageous for smaller companies that do not need large volumes. In addition, for longer print runs it is usually not cost-effective compared to offset.

Customization:

an advantage that many customers appreciate is the possibility of making several versions of the same piece and making a few copies of each one, instead of just one large print run. Errors are reduced and more attention is drawn to commercial material, for example when changing the name or images in a catalog.

Agile reprinting:

it can be reprinted very quickly and at any time to update information that has changed over time. Taking advantage of the low volume, it can be revised at any time, also saving storage space.

Less waste:

you print only what you need, quickly and efficiently. Without proofs and adjusting the stock to the essential, this makes digital printing more environmentally friendly than other options.

Quality:

although offset printing has a long reputation for quality for magazines or catalogs, digital is also very good for certain jobs and has improved a lot. For example, it is widely used in print-on-demand services because it gives good results.

All these advantages have led to the growth of digital printing in recent years, possibly because it has also increased the speed with which projects move in companies and the fact that digital creation has increased considerably and the level of customization and agility that it entails has spread to printing.
