CES Imaging Canon imagePROGRAF TM-350: Fast, Precise, and Vibrant Wide-Format Printing

We see the results of wide-format printing every day, even if we don’t always realize it. From the vibrant billboards that line our streets to the intricate blueprints used to construct our buildings, large-format printing plays a crucial role in bringing big ideas to life. It’s the technology that allows us to create visuals on a scale that simply isn’t possible with standard desktop printers. Think of the detailed architectural renderings displayed at a construction site, the eye-catching posters promoting a new movie, or the stunning panoramic photographs exhibited in a gallery. These are all examples of wide-format printing at work.

Beyond the Home Office: Where Wide-Format Shines

While your home printer might be perfect for printing documents and the occasional photo, it falls far short when it comes to handling large-scale projects. Wide-format printers, also known as large-format printers (LFPs) or plotters, are specialized machines designed to produce high-quality prints on a much grander scale – typically ranging from 18 inches to 100 inches or more in width. This capability opens up a world of possibilities for various industries:

• Architecture, Engineering, and Construction (AEC): Architects and engineers rely on wide-format printers to produce detailed CAD (Computer-Aided Design) drawings, blueprints, and construction plans. Accuracy, clarity, and durability are paramount in this field.
• Graphic Design and Advertising: Graphic designers and advertising agencies use wide-format printers to create posters, banners, point-of-sale displays, vehicle wraps, and other large-scale marketing materials. Vibrant colors, sharp details, and the ability to print on a variety of media are essential.
• Photography and Fine Art: Professional photographers and artists utilize wide-format printers to produce high-resolution prints of their work for exhibitions, galleries, and personal collections. Exceptional color accuracy, fine detail reproduction, and archival quality are crucial.
• GIS and Mapping.

The Challenge of Scale: Why Wide-Format is Different

Printing on a large scale presents unique technical challenges. It’s not simply a matter of enlarging a small image; the entire process requires specialized engineering. Imagine trying to paint a perfectly straight line across a wall that’s 36 inches wide – it’s much harder than painting a small section. Wide-format printing faces similar hurdles:

• Maintaining Accuracy: Ensuring precise ink placement across a large surface area is crucial, especially for technical drawings where even minor errors can have significant consequences.
• Consistent Color: Achieving uniform color density and accuracy across the entire print is essential, particularly for graphics and photography.
• Speed and Efficiency: Printing large images can be time-consuming. Balancing speed with quality is a constant challenge.
• Media Handling: Wide-format printers need to handle a variety of materials, from thin paper to thick canvas, vinyl, and even fabric. Feeding, aligning, and cutting these materials accurately requires sophisticated mechanisms.
  

Enter the TM-350: A Closer Look

The CES Imaging Canon imagePROGRAF TM-350 is a 36-inch wide-format inkjet printer designed to meet the demanding requirements of professionals across various industries. It’s not just about size; it’s about combining speed, precision, and quality in a way that empowers users to bring their creative visions to life. Some of its standout features include the use of pigment-based inks, a sophisticated print head design, and a user-friendly interface.

Ink Under the Microscope: The Magic of LUCIA TD Pigments

One of the key technologies that sets the TM-350 apart is its use of Canon’s LUCIA TD pigment inks. To understand why this is significant, we need to delve into the world of ink chemistry. There are two main types of ink used in inkjet printing: dye-based and pigment-based.

• Dye-Based Inks: Dye inks are made of colorants that are fully dissolved in a liquid, much like food coloring in water. They tend to produce vibrant colors and are generally less expensive. However, they have some significant drawbacks:

  • Water Solubility: Dye inks are water-soluble, meaning they can easily smudge or run if they come into contact with moisture.
  • Fading: Dye inks are susceptible to fading when exposed to light and air, especially ultraviolet (UV) light. This means that prints made with dye inks may not last very long, particularly if displayed in bright environments.

• Pigment-Based Inks: Pigment inks, on the other hand, are made of tiny, solid particles of colorant that are suspended in a liquid. Imagine finely ground spices dispersed in oil. These particles are much larger than dye molecules and are not fully dissolved. This key difference gives pigment inks several advantages:

  • Water Resistance: Because the pigment particles are not water-soluble, they are much more resistant to smudging and running.
  • Lightfastness: Pigment inks are significantly more resistant to fading when exposed to light and air. This makes them ideal for prints that need to last a long time, such as archival documents or artwork.
  • Sharpness: Pigment inks tend to produce sharper lines and text because the particles sit on top of the paper, rather than being absorbed into it.

The LUCIA TD inks used in the TM-350 are specifically engineered for technical documents, graphics, and photos, offering a balance of color vibrancy, durability, and precision. The “TD” stands for Technical Document, highlighting its suitability for applications where detail and longevity are critical. The ink set includes five colors: cyan, magenta, yellow, black, and matte black. The inclusion of matte black enhances the density and sharpness of black areas, particularly on matte media.

Precision Engineering: Unpacking Canon’s FINE Print Head

The print head is the heart of any inkjet printer, and Canon’s FINE (Full-photolithography Inkjet Nozzle Engineering) technology is a key factor in the TM-350’s performance. It’s not just about squirting ink onto paper; it’s about doing so with extreme precision and control.

Here’s how FINE technology works:

1. Microscopic Nozzles: The FINE print head contains thousands of incredibly tiny nozzles – far smaller than the width of a human hair. The sheer number of nozzles allows for a higher density of ink droplets to be placed on the paper, contributing to sharper details and smoother gradations.
2. Precise Droplet Formation: FINE technology utilizes a process called thermal inkjet. Tiny heating elements within each nozzle rapidly heat the ink, creating a vapor bubble. This bubble expands, forcing a precise droplet of ink out of the nozzle and onto the paper. The heating and cooling cycle happens thousands of times per second, allowing for incredibly fast and accurate printing. Crucially, it is not just about small droplets. It’s also about consistent shape and velocity.
3. Droplet Control: The TM-350, thanks to the FINE print head and associated electronics, can precisely control the size and placement of each ink droplet. This is essential for achieving smooth color transitions, sharp lines, and accurate detail reproduction. Variations in droplet size, known as variable dot size, allow the printer to use smaller droplets for fine details and larger droplets for areas of solid color, optimizing both speed and quality.
4. Ink Ejection Consistency: Another factor that sets FINE apart, is its ink ejection consistency. Ejection velocity must be constant.

Color, Calibrated: Understanding Color Management in Wide-Format

Achieving accurate and consistent color is a complex challenge in printing, especially on a large scale. This is where color management comes in. It’s a system of hardware and software that ensures colors are reproduced as faithfully as possible, from the original image on your screen to the final print.

Here are some key concepts:

• Color Spaces: A color space is a mathematical model that describes a range of colors. Common color spaces include sRGB (used for web images), Adobe RGB (used for professional photography), and CMYK (used for printing).
• ICC Profiles: An ICC profile is a file that describes the color characteristics of a particular device, such as a monitor, scanner, or printer. It acts as a translator, ensuring that colors are interpreted consistently across different devices.
• Calibration: Calibration is the process of adjusting a device to ensure that it meets a specific color standard. For printers, this involves printing test charts and using a spectrophotometer to measure the colors. The results are then used to create or adjust the printer’s ICC profile.

The TM-350 supports various industry-standard ICC profiles, allowing users to achieve accurate color reproduction for different applications and media types. While the printer doesn’t include a built-in spectrophotometer, it’s compatible with external calibration tools, enabling users to create custom profiles for optimal results. The included PosterArtist Web software likely offers basic color management tools.

Putting it All Together: How It All Works.

The TM-350 is much more than the sum of its parts. All of its components work in concert:

1. Data Reception: The printer receives print data from a computer via a USB or Ethernet connection.
2. RIP Processing: The Raster Image Processor (RIP) software, either built-in or external, converts the digital image data into a format that the printer can understand. This involves rasterizing vector graphics, applying color management profiles, and generating instructions for the print head.
3. Ink Delivery: The printer’s ink delivery system draws ink from the individual cartridges and supplies it to the print head.
4. Print Head Movement: The print head moves back and forth across the media, precisely ejecting ink droplets according to the instructions from the RIP.
5. Media Handling: The printer’s media handling system feeds the paper or other material through the printer, ensuring accurate alignment and preventing jams.
6. Drying/Curing: The ink dries or cures on the media.
