Download before ordering!
Download and inspect the plan pdf file before ordering any prints, the paper prints will be made from it.
You can use Adobe PDF Reader to open any PDF file, set the zoom to 100% and look at the line quality, use the tape measure tool to check the dimensions. This is your responsibility.
What are you ordering:
You are ordering a print from the main PDF file in this listing, it´s exactly like taking this file in a thumb drive to a local print shop and ask them to make a print.
About the plan source:
You should verify if the source file has the quality for the type of construction you intend to do, we will print the file without any kind of enhancement or scaling.
To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer and set the view level or zoom level to 100% or 1:1 or
full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool make sure all the parts fit together and have the correct size.
In doubt please ask us for an opinion.
We can scale this plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.
You will receive:
Laser Printed plan on good quality Bond paper or/and Tracing Paper and/or Polyester sheet of the PDF file from this listing, depending on what you have purchased.
Rolled sheets, up to 5 in the same cardboard tube.
Envelope, up to 5 sheets per envelope.
Articles and Instructions if they are available and if you order them.
Air Mail, Priority, Priority Insured or Normal mail, according to your choice.
About our printers:
We use professional quality laser OCÉ and Canon printers/copiers, these printers use toner, not ink so the printings will be durable and waterproof.
About the different media types:
Bond Paper: White Bond paper, 80 grams per square meter. Bond Tracing paper: Bond Tracing paper, 90 grams per square meter. Polyester film: High quality polyester sheet incredibly durable, will resist cuts and glue and can be washed (I use it as sail material on my RC sailboats).
We charge by print length (914mm or 91,4cm or 36in. by the length of the print)
This means that a plan 120cm by 150cm will be charged two times 150cm because it will be printed in two tiles, a plan 91cm by 150cm will be charged one time its length or 150cm and a plan 91cm by 40cm will be charged 40cm.
The system will try to fit a plan in the 91,4cm of the printer width in order to reduce the costs or print length to the maximum. This is the same charging method used in any printshop.
We will use paper or waxed paper padded envelopes for folded plans and hard cardboard tubes with plastic ends for rolled plans, depending on your choice.
We ship from Portugal, Europe and use the reliable Portuguese mail system CTT.
CTT has delivery agreements with different entities on each country so if you´re from the US you may have your order delivered by USPS, in the UK may be Royal Mail and so on.
Orders are dispatched on the next or second business day after purchase.
We charge according to the ctt.pt postage table.
Normal Mail: Normal Mail is non traceable, use at your own risk, no insurance, total loss if the carrier loses it.
Priority: Priority Mail is traceable on your local/national mail system, it is not insured.
Priority Insured: Priority Insured Mail is traceable on your local/national mail system and is insured.
If you ordered Priority or Insured your order will have a Tracking Code, to get it please reply to the Paypal notification email and we´ll reply back with your tracking code that you can paste on the website under the top menu "More".
Discount coupons are valid from 3 to 30 days after purchase, you can use them any number of times you like but only once per item order.
The codes are issued in the Paypal invoice, please check the transaction details at Paypal website or in the Paypal email you received after purchase to get your Discount Coupon code.
You are free to post the Coupons online, give them to friends, share them in any way you like.
To use just Copy/Paste the Coupon code (i.e.: TAKE10#6012019) to the text field in the plan listing page to use your discount. No spaces and no manual typing, just copy/paste.
Please keep in mind that when you order a plan it will be printed specifically for you, just like when you go to a local print shop.
Before ordering please make sure that the plan will fit your needs, in doubt please ask us for an opinion.
If you still receive a plan you don´t like we can accept it back if it is in good conditions but we will not refund the postage from the initial order, you will have
to pay the postage to return the plan to us and a 30% re-stock fee will be applied so please, in doubt, please ask us for an opinion.
Orders can be paid with Paypal or Credit Card via Paypal and are shipped to the address on your Paypal account or to the address you set at checkout.
