Open your portfolio and turn to the back. Lift the spine flap to reveal the screw post bindings. Remove screw heads to open binding.

Your new portfolio will have 3-5 spacer tabs and optional double matte end sheets.

Mullenberg Designs Portfolio inserting pages

Remove the spacer tabs and drop in your page stack. Use spacer tabs to fill in the depth of the screw posts leaving about an 1/8″ (3-piece style portfolios) or 1/16″ (full-case style portfolios) of the post. Remove your stack.

Now you can distribute the needed amount of spacer tabs evenly within your pages. Add one spacer tab after your first page, one in the middle of your page stack and one before your last page. If more than 3 tabs are needed just make sure the additional spacer tabs are distributed evenly within your pages to avoid a visual gap.

Replace your spine and back cover (3-piece style portfolios) or spine flap (full-case style portfolios) and replace screw heads. That’s it 🙂 Thank you!

Introducing: New Cover Materials!

Every once in a while we cull through samples of book-cloth fabrics to see if we can add to the offerings available to our customers. We look at the quality and durability of the fabric as well as its visual appeal. We were immediately interested in the new line of Euro-Buckram Fabrics when they crossed our desk. They smacked of urban industrial beauty and seemed a perfect fit for our sensibility.

Maine: Blue Skies and Green Seas


Perhaps it’s the promise of long Maine summer days at the beach or the lack of blue skies  this week (I know that sky is still blue behind all those clouds!!!) that inspired me to pull together these images of Portfolios and Presentation structures that incorporate these beautiful calming colors. Enjoy!

Have a preferred printer already?

Great! We can work with your printer! Let your printer know that our screw post bindings hide 3/4″ of the page’s width in the binding and to plan your image area based on that. So if your image area is 11h x 14w” your page’s final trim should be 11h x 14 3/4″w. We will send your printer a page template for punching holes in your pages to prep them for the screw post binding. If you are working with sleeves you will need to send us one so we can plot the holes in your binding to match your sleeves.  Also tell your printer we recommend 2 scores in each page, one at 7/8″ and one at 1″ from the spine. These scores help to maximize the ease with which your pages turn and lay flat in your portfolio.

Printing on your own?

Here are some helpful tips:

The final trim of your page: When considering your final paper trim, take into account your art board (e.g. 11h x 14w landscape) and add an extra 3/4″ on the left side of the page, which would make your final trim for an 11 x 14 landscape image, 11″h x 14 3/4″w.  This extra 3/4″ on the left side of the page is where the holes are punched for the post binding and is hidden in the binding.

– if printing full-bleeds it’s recommended to print on larger format paper, and when building your files to extend your bleeds 1/8″ on all bled sides beyond your crops. For example, if you’re printing 11h x 14w full-bleed images, we suggest printing on 13 x 19 paper, and extending your bleeds on the top, bottom, fore edge and into the gutter 1/8″.

Pre-scored and Pre-drilled Paper at Pinazangaro: What is really great about this paper option is the trimming, scoring and punching is done for you. The Lasal paper is a lovely double-sided matte paper with a smooth finish. If you are planning on printing any full-bleeds this paper may not be an option for you.

Moab Paper has many great paper options, the Entrada Rag is a beautiful cotton rag paper with a rich surface that really holds your ink. The Chinle line offers this paper in a Pre-scored and Pre-drilled option.

Hahnemühle Paper offers a gorgeous array of Digital FineArt paper to peruse with choice of grain direction.

Prepping prints for your Portfolio:

Trimming, Punching, Scoring & Hinging


The final trim of your page: When considering your final paper trim, take into account your art board (e.g. 11h x 14w landscape) and add an extra 3/4″ on the left side of the page, which would make your final trim for an 11 x 14 landscape image, 11″h x 14 3/4″w.  This extra 3/4″ on the left side of the page is where the holes are punched for the post binding and is hidden in the binding.

We recommend if you’re printing full-bleeds that you print on oversize paper with crop marks and extend your bleeds 1/8″ past the crops.  For example, if you’re printing 11h x 14w full-bleed images, we suggest printing on 13 x 19 paper, and extending your bleeds on the top, bottom, fore edge and into the gutter 1/8″.  This assures when final trimming that there will be no hairline white lines.


All of our portfolio books are built with a hidden screw post binding making it easy for you to add and remove images. If you are not using a pre-scored/drilled paper, you will need to punch holes in your pages that line up with the binding. We will send you a page template as a reference for punching your own pages, including a couple score references, we score twice from the left edge of the page at 7/8″ and 1″. You can get a hand held punch at Talas we suggest the 1/4″ drive punch.

Scoring vs. Hinging

Scoring & Hinging: scoring or hinging your prints helps your portfolio pages turn with ease and lay flat in your new portfolio.


Scoring works great for matte papers. Scoring is the process of making a line or depression in your paper to help create a fold. This gives your pages a memory to fold at the spine and helps your pages turn with ease and lay flat in your portfolio book. To encourage a scored page to lay flat, we recommend once the book is loaded to turn each page and run your palm down the gutter to begin giving these scores a new memory. We typically score the pages twice at 7’8″ and 1″ from the spine/left side of the page. If you are printing full-bleeds, the scores will live on top of the image.  Scored pages work beautifully for trucking images across the gutter as there’s no break in the image.

Mullenberg Designs scored page


Hinging is the option to go with if you are printing on a luster or satin surface. Scoring will crack the emulsion on these papers and ruin your print. To hinge a page we add 1 1/2 inch strips of fabric to the spine side of your page. There are hinges available commercially as well if you want to do it yourself! Check out these hinges from Pinazangaro. Hinging your pages allows for ease in turning your pages and your prints will lay exquisitely flat in your portfolio book. The drawback with hinged pages is you can’t successfully truck an image across the gutter as there will be a break in the image.

Style: 3-Piece or Full Case Portfolio?

Mullenberg Designs offers Portfolio books in 2 distinct styles. The 3-Piece and The Full Case style Portfolio. We often get asked which one we recommend; What are the advantages of one over the other? Well, we love them both. They cost the same and are both built with screw post bindings making them equally easy to get into, to add or remove images.

So how do you choose one? Here are some images and features of both styles to help you with this important decision.

The 3-Piece:

As its name suggests the 3-Piece style Portfolio is built in three separate components: a front cover, back cover, and a separate spine. The separate spine piece allows you to add a splash of bold color to your exterior design without an additional cost.

The Full Case:

The Full Case style Portfolio has the look of a traditional bound book. It is built in one piece with an interior spine component. This streamlined style can be customized with a 2 fabric cover.

Cover Materials: Color, Texture & Finish

At Mullenberg Designs we offer a wide array of cover materials to customize your Portfolio Presentation. We separate our cover materials into three categories: Coated, Uncoated and Leatherette.

Coated Fabrics:Mullenberg Designs Cover Fabrics: coated

Coated: These ‘coated’ fabrics are 100% cotton. They are durable and have a contemporary look and feel. They are treated with an aqueous coating making them stain and mildew resistant and easy to clean with the wipe of a damp cloth. These fabrics pair nicely with either the Uncoated or Leatherette fabrics.

Uncoated Fabrics:Mullenberg Designs Cover Fabrics: uncoated

Uncoated: These high quality, 100% rayon book cloth fabrics have a natural finish. They offer the look and feel of linen and come in a variety of colors. Note that the lighter colors are more vulnerable to staining so we recommend using them for interior cover materials. These fabrics pair nicely with the Coated and Leatherette fabrics.

Leatherette Fabrics:Mullenberg Designs Cover Fabrics: leatherette

Leatherette: A polyurethane cover material with a look and feel of calfskin. Durability and easy clean-up make this fabric a great choice for a cover material. These fabrics pair nicely with the Coated and Uncoated fabrics and take a beautiful blind deboss.
