Follow these simple tips when ordering your custom screen printed t-shirts for a quicker and more trouble free experience.

The first thing to be discussed is the difference between screen printing and digital garment printing. In general screen printing is a more labor intensive process than digital printing and requires color separations and individual screens to be made for each color in the design. Digital garment printing on the other hand is simply a shirt printed in a printer much like the paper printer that most of us use everyday to print photos or documents. t shirt printing

The subject of a different article, but for now suffice it to say that digital garment prints work better on white or light colored shirts and are better suited to short run orders.

Artwork is a prime factor in getting your shirts printed in a timely manner. The better the artwork, the better the finished product. I’m sure you have heard the old adage “Junk in, Junk out”, well, this is truly the case when it comes to screen printing. Artwork falls into two basic groups depending on what software program produced it or where it came from.The first group I will talk about are Raster images. Raster images will have file extensions such as .bmp, .jpg ,.tif, or .psd and are pixel maps which are dependent on resolution (dots per inch ) to maintain clarity. The higher the dpi, the clearer the image will be. While Raster images are great for digital printing, they can be problematic for screen printing in that file sizes are typically large and color separations can be more difficult, not to mention the pix-elation that occurs when up sizing images. If a Raster image is the only option that you have, be sure that it is sized appropriately for screen printing and in a high resolution (at least 300 dpi original resolution) before sending to avoid additional art charges or unnecessary delays.

The second group is called vector images. Vector images are preferred by screen printers due to their flexibility in resizing without degradation, smaller file sizes and ease of color separations. Typical file extensions for vector images are .ai, .eps and .cdr. Vector images use point coordinates and mathematical equations to define elements in an image as opposed to pixels and can therefore be re-sized without discrimination. Vector images are your best bet for getting a fast turnaround and avoiding additional art charges when ordering your custom t-shirts printing.

Color selection is also something to be considered ahead of time to help expedite your order. Your printer will need to know the pantone colors that you would like to be used in your t-shirts printing.custom t shirts

Shirt Selection can be confusing, but basically there are two main fabric weight classes to select from, 5.6 oz or 6.1 oz. Beyond that style will need to be decided, Ladies or Men’s, short sleeve or long sleeve, pockets or not, scoop neck v-neck or regular, as well as shirt color. It will save much time if all of this is decided ahead of time, and whether you purchase your shirts from our company or not, please feel free to shop and make selections with our online Catalog If your custom t-shirts printing order includes any individualization such as names or numbers prepare a list displaying properly spelled names, numbers, and sizes to help avoid confusion.

We hope that this article has been helpful in making a custom screen printing order a little less daunting.

General Principles of Sewage Treatment

General Principles of Sewage Treatment

Raw sewage and septic wastewaters contain a variety of contaminants. Many technologies are available to render the sewage suitable for safe discharge to the environment. These include those used in the municipal treatment works that receive sewage discharged to public sewers in the nation’s developed areas; conventional on-site sewage treatment that uses a septic tank and soil absorption field commonly used in rural areas; and the alternative on-site technologies that form the focus of this publication. Most sewage treatment technologies operate by combining basic physical, chemical, and biological processesSurface Aeration - Waste Water Treatment
1. Primary treatment removes solid chunks and particles from raw sewage through gravity separation and/or screening. A septic tank is the most common primary treatment device in on-site systems. In alternative systems, the septic tank is commonly outfitted with an outlet filter, to capture solid particles that are too small or too light to settle. When used with conventional septic systems, an outlet filter will extend system longevity and improve performance. The partially-treated liquid discharged from primary treatment is called primary effluent.

2. Secondary-treatment processes (also called microbial digestion) receive primary effluent. Most secondary-treatment processes move the effluent through an aeration process environment that is favorable to aerobic microorganisms, those that thrive in atmospheric oxygen (O2) environments. The following wastewater renovation processes occur during this treatment:

Pathogenic microorganism populations are reduced. The vast majority of microorganisms found in sewage thrive within the human digestive system, an environment where oxygen does not occur as O2. Consequently, these organisms are not well adapted to aerated environments. Within secondary-treatment devices, some microorganisms (including most pathogens) perish as a result of exposure to O2.

Other organisms, including predators that consume pathogens, do thrive in an aerobic environment, sustained by the rich mix of O2 with H2O, biodegradable organic compounds, and essential nutrients that comprises sewage. Where the effluent passes through secondary treatment media with small pores (such as a sand filter, or natural soils), pathogen numbers are also reduced via physical straining.

Biodegradable organic contaminants, such as dissolved organic substances, and organic particles, remaining in the effluent after primary treatment are removed.
The microorganisms in the aerated secondary-treatment medium consume and metabolize biodegradable organic compounds, deriving energy by breaking the carbon-carbon bonds and converting the organic carbon to carbon dioxide (CO2).

Small particulate contaminants are removed. Where the filtration media are comprised of mineral particles with small pores (such as a natural soil or a sand filter), particulate contaminants are removed via physical screening; biodegradable components of the particles captured in the fine pores are consumed by the resident aerobic bacteria. wastewater treatment via surface aeration
The partially-treated liquid discharged from secondary treatment is called secondary effluent.

3. Advanced treatments are optional processes that may be applied to remove additional contaminants from secondary effluent prior to dispersal. Advanced treatment is usually included only in systems intended to discharge directly to the land surface, or to surface-water streams. Advanced treatment processes designed to remove additional nitrogen and phosphorous from the effluent are sometimes necessary to protect water quality in streams receiving treated effluent discharges.

4. Disinfection systems often rely on chlorination, ozonation, or ultraviolet light. Systems that discharge treated effluent where there is a potential for direct human exposure (i.e., discharge to surface waters or the soil surface) are often required to disinfect the effluent so as to eliminate potential hazards due to human exposure.
Effluent that has been disinfected, and has received advanced treatment, is called tertiary effluent.
Treated effluent must be discharged to (or dispersed in) the environment. Secondary effluent is commonly dispersed in soils below the surface, while tertiary effluent may be discharged to flowing waters (such as a surface-water stream) or on the soil surface. Surface discharge or dispersal typically requires a permit from an agency responsible for protecting surface-water quality as well as an on-site septic system permit.
